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 $C_1$ symmetry, and the unit cell symmetry of the trigonal space group is $C_3^1\text{[C3]}$ . Raman spectra of the lattice vibrations are presented.
