Ionic Interactions in Crystals: Infrared and Raman Spectra of Powdered Ca(NO3)2, Sr(NO3)2, Ba(NO3)2, and Pb(NO3)2

Abstract
Infrared and Raman spectra have been recorded for room‐temperature phase powdered samples of Ca(NO3)2, Sr(NO3)2, Ba(NO3)2, and Pb(NO3)2. The spectra are interpreted in terms of a factor group analysis. Considerable multiplet band structure is reported for the first time.
