Determination of inhomogeneous trace absorption by using exponential expansion of the absorption Pade-a

摘要

Abstract: A method for inhomogeneous, molecular gas integrated absorption calculating is developed by using partial absorption, that depend on mean absorption coefficients K$-n$/ obtained in analytical form. These coefficients are evalutated numerically or analytically for the actual frequency dependence of the spectral absorption coefficients. A procedure for determination of mean coefficient for gas mixture is discussed.!
