Angular-Correlation Functions of Diatomic Rotators in Alkali Halides

Abstract

For the first time, angular-correlation functions of diatomic rotators in solids have been determined experimentally using vibration-rotation spectra. As samples we used ${\mathrm{OH}}^{-}$ and ${\mathrm{OD}}^{-}$ in KCl. Maxima and minima of the correlation function show an isotopic shift.
