The HETCOR (HETeronuclear CORrelation) experiment produces a two dimensional spectrum that correlates protons and a heteronucleus, typically carbon. It is one of the earliest 2D experiments and is best used with a direct detect probe. Today, the HETCOR experiment has been replaced by the HSQC experiment. This post will discuss why the HETCOR experiment is now little used and under what circumstances you might still want to use it.
