Near and Far Wing Pressure Broadening Theory for Application to Atmospheric Absorption.

Abstract

A new theory of far wing pressure broadening is presented. The theory rigorously satisfies the Fluctuation-Dissipation Theorem, and includes all possible line coupling effects. The starting point of the theory rests on the observation that far wings are determined by the binary collision approximation in its most naive form. The theory is then developed in terms of two-body T-matrix of scattering theory. Results of near wing calculations of halfwidths and pressure shifts for H2O-N2 and H2O-H2O are briefly summarized.
