Shape of Collision-Broadened Spectral Lines

Abstract

Van Vleck and Weisskopf1, in an interesting paper, have shown that the well-known Lorentz formula for the shape of a spectral line is incorrect except at frequencies close to the resonance frequency. Since this formula has been considered to be correct for a great number of years, it may be of interest to record that, using a different method, I had reached the same conclusions2 as Van Vleck and Weisskopf. This method, although originally developed for the case of a rigid dipole oscillating about an equilibrium position, can easily be adapted to harmonic oscillators.
