Abstract
A simple classical method is used to calculate the shape of the emission line and Raman spectrum line of a molecule which behaves like a damped harmonic oscillator. The shapes found, which are similar for the two cases, differ appreciably from the Lorentzian shape and from the shapes found by other authors if the line width is of the same order of magnitude as the natural frequency. Such a situation arises in ferroelectric crystals at temperatures close to that of a second-order phase transition.
