Epoxides, like ethers, generally have no easily distinguishable IR band but rather are identified based on: Knowledge that oxygen is present in the molecule; Absence of a C=O band (1650-1800 cm -1) Absence of an O-H band (3200-3700 cm -1. There may actually be an assignable C-O band between 1300-1000 cm -1 in this molecule.
Webacetonitrile), this signal is a 1:2:3:2:1 quintet with a splitting of ca.2 Hz. (3) In contrast to what was said in note 2, in the 13C spectra the solvent signal is due to the perdeuterated isotopomer, and the one-bond couplings to deuterium are always observable (ca.20-30 Hz).
