Fall 2017 First Order Spectra For a spectrum to be 1 st order the D n between the chemical shifts of any given pair of nuclei must be much larger than the value of the coupling constant . 1. Diffusion Ordered Spectroscopy. Provides a way to separate different compounds in a mixture based on the differing translational diffusion coefficients (differences in the size and shape of a molecule). 3/9 . Lecture.
