Polarized Infrared and Raman Spectra of Single-Crystal CsNO3-II

Abstract

Polarized infrared and laser-induced Raman spectra were obtained for single-crystal CsNO3-II. The spectra in the region of the internal vibrations of NO3− indicate that these ions are positioned at sites having C1 symmetry, and the unit cell symmetry of the trigonal space group is C31[C3]. Raman spectra of the lattice vibrations are presented.
