INFRARED-INDUCED CONFORMATIONAL ISOMERIZATIONS OF ALLYLAMINE AND ALLYL ALCOHOL IN LOW-TEMPERATURE MATRICES

Abstract
The infrared spectra of allylamine and allyl alcohol have been studied in low-temperature matrices. In argon matrices these molecules show rapid spectral changes upon exposure to the radiation from the light source of an infrared spectrophotometer. These spectral changes arise from the conformational isomerizations from a rotational isomer with the cis conformation about the C–C bond to those with the skew conformation. No such conformational isomerization has been observed in nitrogen matrices.
