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.Keywords
