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.  

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.
