The electron-impact mass spectra of the E- and Z-isomers of the α,β-methyl substituted esters of β-phenyloxiranecarboxylic acids have been studied.

It was established that the 3JCH spin-spin coupling constants and chemical shifts in the 13C NMR spectra of the cis and trans isomers of oxiranecarboxylic esters are stereospecific.The signals for the methyl groups of the cis isomer are 4-7 ppm upfield from the signals for the trans isomer.The 3JCH constant due to spin-spin coupling of the 2-CH3 (or 3-CH3) group and the proton at the C3 (or C2) atom amounts to 2 Hz for the cis isomer and is absent for the trans isomer.
