NMRQA 2.6



Publisher Description



NMRQA is an App containing about a hundred and sixty five simple revision questions and answers on NMR. This App is not intended for people who are not familiar with the basic concepts of NMR. Obviously it is not intended for NMR experts. It is intended for scientists and research students who are using NMR and want to check their knowledge of basic NMR facts, experimental parameters, signal processing, relaxation and methods of obtaining maximal signal-to-noise. NMRQA may also be useful for undergraduate students undertaking advanced courses on 1D-NMR. It only gives short single or two sentence answers and so it is not intended to replace textbooks or user manuals but it may help you understand them. If you want to analyze pH dependent changes in chemical shift you may find the program "ppmfit" in the Mac app store useful. If you want to estimate the contributions of dipolar relaxation and relaxation by Chemical Shift Anisotropy(CSA) to carbon-13 T1 values you should find "T1calc" in the Mac app store useful.

It does not contain the material covered in most undergraduate lecture courses or elementary texts and it is limited to 1D NMR. Its focus is on practical aspects. It is hoped it will help you interact with NMR operators and set up your own NMR experiments. There is a list of the topics covered below.


Topics include:-
Larmour frequency and NMR operating frequency.
Chemical shift.
Gyromagnetic ratio.
Locking and shimming.
Sensitivity and natural abundance 1H,13C,15N, 19F and 31P.
Pulse widths.
