The Raman spectra of N-14O2 and N-15O2 solids at 20 K

The Raman spectra of N-14O2 and N-15O2 have been studied at 20 K. The far infrared of N-14O2 at 20 K was also measured. The data were assigned on the basis of a C-sub 2 nu molecular model. Normal coordinate calculations were performed for a variety of assignments. The assignment that yielded the best fit is presented. The solid state effects are discussed.
