Abstract
An alternative description of the k=0 librational spectrum of solid α‐N2 is given. A variational method where the wavefunctions of the hindered rotator are expanded in terms of spherical harmonics is used. The present calculations are limited to electrostatic quadrupole—quadrupole interactions. The k=0 librational frequencies are compared with the results obtained by classical lattice dynamics and another variational method as well as experiment.
