Any PC built in the last 8 years is good.
INMR ACRONYM MAC
iNMR is available for the last 3 major versions of Windows and 6 versions of Mac OS, which means 59%of the active computers.
INMR ACRONYM LICENSE
The same license is valid for many kinds of computers.The optional keyboard shortcuts are easy to memorize and increase your productivity. More screen estate is available for spectroscopic contents, you are not distracted by unnecessary widgets. The graphic interface is the simplest and the tidiest.iNMR is the only NMR program to follow the advice and the results are amazingly clear plots, fast drawing of large matrices and assured support by future versions of Windows. Microsoft explicitly recommends to embrace Direct2D as the drawing API for new applications.You can't say the same thing about other NMR programs, which are built upon several intermediate layers of software. iNMR is written in C/C++ and takes for itself only a minimal amount of disc space and memory. iNMR is a native Windows application that directly calls the traditional Windows APIs, something unique in the NMR field.If you don't know the language we'll write the scripts for you. Only two NMR programs include a Lua interpreter: CARA and iNMR. Lua is a first-classprogramming language which is the ideal in terms of versatility and speed. You can further extend the functionality of iNMR with your own scripts, thanks to the embedded Lua interpreter.This is what you pay for when you buy a license. If necessary you can receive a patched or customized version in a matter of hours. You'll receive email supportdirectly from the author, 360 days per year, from 8 AM to 12 PM (Central European Time, UTC+2 from April to October, UTC+1 otherwise).
INMR ACRONYM SOFTWARE
Your experimental data remain readable by all other NMR software in circulation. Any additional information that you generate is stored into short and readable XML files that you can open with countless external applications. iNMR always works with the original spectrometer files. With iNMR you just pay once and receive years of upgrades and support. Most of our competitors, instead, give you the basic functionality only and then ask you more money for the additional modules and the yearly upgrades. When you buy a license you get everything.
The ion could move between the two nitrogens. This is when the signal is the broadest and when the rate of exchange can be calculated with the highest accuracy.Ī few years ago I wrote a tutorial on a complex between a ligand with two nitrogens and a platinum ion. At coalescence, instead, even a small change in the rate has a dramatic effect. At the fastest and slowest extremes, even a drastic change in the rate has little effect on the spectrum. To calculate the rate, we perform Lineshape Analysis, that is we compare a simulated spectrum with the experiment. If we increase the magnetic field, the effect is similar to cooling. More exactly, the appearance of the spectrum depends both on the rate of exchange and on the difference (in Hz) between the two peaks. At higher rates the single signal is so sharp that we don't mention Dynamic NMR anymore. Warm the sample and the exchange becomes faster and faster: you see a single signal, but quite a broad one. If the exchange is a little faster, you see two broad signals in 1-D. If the exchange is slow, you see nothing in 1-D, but you see a cross-peak in the EXSY spectrum (another name for the more familiar NOESY). What matters is the rate of exchange between the two states. The principle is so general, that the kind of chemical bonds that are created and destroyed is not relevant. "Chemical Exchange" is the expression that encompasses everything. Common examples are: the equilibrium between conformers complexes that can have two different structures, etc. When a nucleus moves between two (sometimes more) chemical states we have Dynamic NMR.
