The nuclear magnetic resonance and infrared spectra of five N-vinyl compounds and the corresponding N-ethyl compounds have been observed in order to obtain detailed information about the N-vinyl group. Resultant data indicate that one might prove the presence of
N-vinyl by two characteristic infrared maxima in the region of 1390 t o 1300 cm−1. The NMR spectra of the N-vinyl protons conform to the expected ABX pattern. The chemical shifts do not permit differentiation from other vinyl types.
