Abstract
A single crystal study of hydrazine sulfate and deuterium-substituted hydrazine sulfate utilizing both polarized Raman and FT-IR reflectance spectroscopy is reported. External optic modes of the sulfate ion have been distinguished from those of the hydrazinium ion for the first time. Reflectance spectroscopy allowed the identification of the ν 3 modes of the sulfate ion in a spectral region containing the N-H bending and deformation modes of the hydrazinium ion. The spectroscopic data indicate a very slight degree of interionic coupling between the sulfate and hydrazinium ions. Transverse optic modes derived from the reflectance spectra correspond quite well to the frequencies observed in the Raman spectra.
