Аннотация
The Raman spectrum of solid α-N2 has been investigated between 12°–35.5°K. Two lines were observed at 31.5 and at 35.8 cm−1, with intensity ratio 3.6 in favor of the lower-frequency line. A calculation of the scattering intensities was carried out assuming additivity of molecular polarizabilities. Consideration of relative intensities led to the assignment of the three predicted Raman-active librational lattice vibrations, assuming a close coincidence of two of these modes. The assignment is supported by an independent frequency calculation.
