On the Infrared Spectrum of Hydrazine

Abstract
The absorption spectrum of hydrazine was reexamined in the region 1.5–25μ with a prism instrument. In the vapor some twenty bands were found of which a few are appreciably different from previous data. The low frequency fundamentals showed enough structural details to make possible a rough calculation of the rotational constants of the molecule. Because of extensive overlapping the identification and assignment of certain bands remain doubtful. The absorption spectrum of the liquid and that of the solid at −70° were also measured over a limited range.
