✦ Synopsis

Exact expresstons for the temperature dependence of the mean frequency and width of an absorption spectrum for an allowed transition between a harmonic lower state and a linear repulsive upper state potential are derived. This is suffkient information to obtam a Gaussian approximation for the absorption spectrum. The present results for the first two spectral moments are exact, and therefore represent an improvement over the Sulzer-Wieland equation in its original or modified forms.
