On the Infrared Spectrum of Hydrazine Matrix-Isolation Studies of the System NH2NH2:N2 (I)

Abstract

Matrix isolation spectra of the system NH₂NH₂:N₂ were obtained in the region 4000–270 cm^—1 at 4.2°K. Spectra taken in this manner are free of complications due to association, over‐all rotation, etc. The unusual features of these spectra are that the bands usually assigned to the bending modes which are present in gas‐phase spectra at ∼1500–1600 cm^—1 are not found; and, that the torsional mode is apparently split. Anomalous behavior for the 6.3‐μ gas‐phase band was observed.
