Intermolecular vibrational coupling associated with the 2ν2 features of the Raman spectrum of strontium nitrate

Abstract
A comparative study of the Raman spectra of chemical and physically mixed crystals of Sr(14NO3)2 and Sr(15NO3)2 shows that the doubled features observed in the 1630 cm1 (2ν2) region result from intermolecular vibrational coupling and not from multiple site occupancy.
