THE ELECTRONIC ABSORPTION SPECTRUM OF METHYL AMINE AND ITS DEUTERIUM DERIVATIVES

Abstract

Author Institution: Department of Chemistry, Northeastern UniversityThe absorption spectra of methyl amine, methyl amine-$d_{2}$, methyl-$d_{3}$ amine and methyl-$d_{3}$ amine-$d_{2}$ have been measured photoelectrically in the 1050-2500 {\AA} region with a 1-m monochromator having a $1.0 {\AA}$ band-width. Only the first two electronic transitions at 2150 and $1740 {\AA}$ show extensive vibrational structure. The deuterium derivatives have aided in the vibrational analysis of the previously unassigned $1740 {\AA}$ band. The electronic structure of methyl amine will be discussed in relation to that of ammonia and other simple alkyl amines
