Then you have landed on the right site! Here are the download links for the Mac and the Windows version. You can use iNMR in demo mode and it is completely legal. When you have finished processing (and, if you like, annotating) the spectrum, you can save it as a PNG file. You will be using a general Mac trick to generate a picture from the screen. ACD/NMR Processor Academic Edition is a handy application designed for the students that need to analyze data received from chemical instruments. The program can be used even away for the lab in order to create spectral manipulations or data analysis. The application can also attach chemical structures and assign correlations to the analyzed data.
ConcurrentHashMap is a better choice than synchronized HashMap if you are using them as cache, which is the most popular use case of a Map in Java application. ConcurrentHashMap is more scalable and outperforms when a number of reader threads outnumber the number of writer threads. LinkedHashMap will iterate in the order in which the entries were put into the map 'Hashtable' is the generic name for hash-based maps. In the context of the Java API, Hashtable is an obsolete class from the days of Java 1.1 before the collections framework existed. It should not be used anymore, because its API is cluttered with obsolete methods that duplicate functionality, and its methods are synchronized. There are two big differences: 1) The LinkedHashMap is ordered but not thread safe. 2) The ConcurrentHashMap is thread safe but not ordered. If you need an ordered thread safe map, then maybe ConcurrentSkipListMap might be a better choice (but maybe not.). 1) First and foremost difference between LinkedHashMap and HashMap is order, HashMap doesn't maintain any order while LinkedHashMap maintains insertion order of elements in Java. 2) LinkedHashMap also requires more memory than HashMap because of this ordering feature. As I said before LinkedHashMap uses doubly LinkedList to keep order of elements. Linkedhashmap vs concurrenthashmap.
Consider TopSpin, for example. I remember its original price was in the range € 4000-5000. At the beginning of the month, I have visited an industrial lab where they had recently purchased a license for off-line processing. They told me they had paid € 3000 for TopSpin. They had also considered a solution by ACDlabs, but after receiving a quote of € 10,000 they renounced with disgust. The main reason why they prefer TopSpin is that it is possible to process the spectra directly on the spectrometer, with great saving of time. When back into the lab, they simply print the already processed spectra.
Less than 24 hours later I had a pleasant talk with Angelo Ripamonti, from Bruker Italy. He gave me different figures. The price of a license is € 2,000, complete with box, cartaceous manual and CD. They also have an electronic edition, called 'Topspin Student Edition'. It is the same product, the license expires after 3 years and costs € 99 (as far as I understand, there is no after-sale support; I am not sure, though). With my great surprise, Angelo said that they hope the students will familiarize with TopSpin during their PhD period and remain faithful to it. I used to think that TopSpin was by far the most famous of all the NMR programs; evidently they are not so sure and fear the competition.
On one thing we agreed all along the line: the chemical industry has completely disappeared from Italy (if we are allowed to measure it by the number of magnets being sold). If I could, I would also close the Italian universities (what's its purpose, if there is no industry? the local job market wants nurses, not chemists), but that's another story (Angelo hopes the Universities will grow and buy more magnets).
I told Angelo that I had noticed that ACD had their own 'academic edition', which is completely free. I myself have received a copy, though never used yet. I asked for his opinion: could the ACD move be a reply to Bruker's Student Edition? 'No', he said, 'they are making a lot of money from their NMR database'. Translation: ACD is the only competitor in the field of NMR database and they want to monetize as much as they can while the favorable situation persists. Indeed, the 'price' I paid for the NMR processor was my email address, which they have already used to advertise the database.
Bruker is also lured by this segment of the market. They bought Perch and are working on it to make a new product that will predict the chemical shifts from the structure. Not the same thing as a database, but with the same purpose.
As my readers know, I had long waited to try the ACD program, because I started this blog with the intention of writing reviews for all the software in existence. Time passed and I have different pastimes today. If I haven't found the time yet to study the Processor and write a review, there are very few chances I can do it in future. The mere length of the manual discourages me. I want however to comment on their commercial move.
(1) It is not correct to first sell a program to several universities and then to give it for free to the rest of the world. Unless they give the database for free to those universities that paid for the processor. That would be a fair compensation. What about, however, the universities who already have bought both products? What about those who never bought anything? After this precedent, how can ACD convince somebody to pay for one of their products, when there's the risk that it becomes free after a few years?

(2) People see with different eyes a program that is free starting from version 1 and a program that is free starting from version 12. Consider, for example, Internet Explorer. It was born as a freeware and it was a huge success, actually a monopoly. It still accounts for 45% of the market. Firefox accounts for the 32%. Opera, instead, started as a commercial product before becoming free. Its share of the market is a disappointing 2%. What people feel is that if the former commercial product was not good enough to sell copies, it is not good enough to bother with.
(3) I don't know exactly why, but ACD has not been lucky, so far, with free programs. Consider their ChemSketch, for example. I have never found a bad review, while I always hear people complaining about ChemDraw. Somehow the latter remains the undisputed no. 1 in the field. Why?
(4) If you want your product to become popular, making it free is a good move, but giving it a catchy name is as much as important. People at ACD have always lacked in inspiration. 'ACD NMR Processor Academic Edition' is the less memorable of the names. Even a distasteful name like 'BottomSpin' would have proved more effective.
(5) If you analyze the situation in detail, this product is still far from being 'free'. Whenever you print, the program adds a red line reminding it's not to be used for commercial purposes. The file format is proprietary and not recognized by all the programs (you are locked-in). There is a potential risk that the program becomes commercial again in future.
The battle has reached the first result. It has created a barrier. If a new competitor wants to enter into the arena, its product must be at least as good as today's free programs (and there are at least 3 formerly commercial programs that are available for free today). Given that it costs a lot of time and money to create a new NMR program, while the prices keep falling, the barrier is very high. We are not going to see any novel program in the next decade, neither free nor commercial. If all the investments are made in the field of databases and predictors, even existing processing programs are not going to be revamped, but simply refreshed.
Do not think that users are happy and programmers are sad. Not at all! After 4 years, the most read page of this blog remains 'TopSpin Free Download' and readers who comments there are angry as before (the page exists, but there is nothing to download!). All the programmers I am talking with, on the other hand, are quite glad: their programs are selling and nobody went in bankrupt in the last few years, despite the financial crises. Apparently a point of contact has been found between the two sides. The prices are more reasonable than they used to be a decade ago, the programs are better and many customers prefer to pay if they can receive a good service in addition to the product.
