摘要
Abstract Improved knowledge of the vibrational frequencies of gaseous secondary aliphatic amines is obtained by means of Raman and of infrared spectra, the latter with improved resolution. Better assignments of the CH deformation and CH stretching vibrations of gaseous dimethylamine and N -deuterodimethylamine are given. The NH stretching vibration of gaseous dimethylamine, hitherto insufficiently known due to its low i.r. intensity, is determined unaffected by superposition of other vibrations. The splitting of the NH stretching vibration of gaseous diethylamine due to rotational isomerism is found to be smaller than previously assumed. It has been detected only in the Raman spectrum. The band splitting for gaseous ethylmethylamine has been observed in the i.r. spectrum.
