Classical radiative damping of symmetric top and asymmetric rotor molecules (H 2O)

Abstract

The broadband rotational emission from a symmetric top molecule and H 2O, as a special case of an asymmetric rotor molecule, is solved in the classical limit. The perturbation solution is based on the well supported assumption that the primary contribution to the dipole acceleration comes from free rotor dynamics. Relations are presented which enable the determination of power and total emission into an arbitrary band, without further integration.
