Yes. There are many, many types of spectroscopy. This ones involves magnets and radio frequencies, and can (potentially) tell you things about a liquid which is placed into a thin/tall glass tube. The principle under which it operates is the same as an MRI scanner; however, rather than making pictures, it makes squiggly lines. It is not a [https://www.youtube.com/watch?v=9Gq3UEAiWio Gas Chromatograph], nor a Mass Spec, as a few have called it...

Unlike some other techniques which allow for elements to be looked at (ICP-MS, ICP-OES, XRF, etc.), this one is concerned with compounds and specifically with Hydrogen or Carbon. It can be used to elucidate the structure of a compound and so lends itself to organic compounds. Only certain elements (or more accurately, certain isotopes of those elements) are NMR Active. These are elements who have an odd number of protons or neutrons.

It can be used to determine the structure of a compound and so lends itself to organic compounds. Only certain elements (or more accurately, certain isotopes of those elements) are NMR Active (meaning, in essence, they will behave like magnets), and it is through putting those into resonance that we can learn more about how they exist within a sample.
