Relative vibrational spectral intensities of the internal modes of phase II potassium nitrate

Abstract
The infrared and Raman vibrational spectral intensities of the internal modes of KNO3(II) are readily understood when it is recognized that the crystal structure (Pmcn,D162h) is a distortion of a (P3̄m1,D33d) lattice. To a first approximation it is the selection rules of this latter lattice which are obeyed by the internal modes of the NO−3 group.
