Orientation ofNCOin KBr derived from polarized Raman scattering

Abstract
The recently introduced ‘‘behavior-type’’ analysis [J. F. Zhou, E. Goovaerts, and D. Schoemaker, Phys. Rev. B 29, 5509 (1984)] of polarized Raman spectra of vibrational modes is a unique method to determine the orientation of static linear molecular impurities in cubic lattices. The NCO defect in KBr is shown for the first time to possess C3v point-group symmetry.
