Jun 15, 2012 · So the questions come back to the first statement about whether NMR analysis alone can be used to establish, distinguish, or rule out structural candidates. Of course this is a big job because to truly be 100% certain that you've got the correct structure you need to rule out all other possible alternatives.
Nov 25, 2017 · On the site I practice on, some problems have IR while some don't. But we are expected to use IR as well on the actual test, and frankly using the IR makes the problem a bit easier. Having a C NMR kinda suffices when there isn't a IR to identify groups like carbonyls, ethers, or alkynes. And yea ik most of the major signals.

A virtual NMR simulator package intended to allow students to learn and practice the NMR instrumental techniques while saving rather expensive spectrometer time and avoiding equipment damage due to improper use.
Now the idea with NMR is to tune the magnetic field frequency to $\omega_+-\omega_-$ (the energy spacing$/\hbar$) of the original system. If you can set up your experiment to (roughly) do that, (and solve the DE's with a Rotating Wave approximation) you get these results for the time dependence of the samples' population:
