Abstract
An evaluation is made of the absorption coefficient of a diatomic molecule in the case where the upper electronic state potential is represented by an exponential function and the lower state by a harmonic oscillator. The matrix element was evaluated exactly by numerical methods and approximately by the method of stationary phase. The results by these two methods are in good agreement with the experimental data on O2 and F2. Discrepancy at the short wave length side of the oxygen Schumann-Runge continuum persists for all methods of theoretical calculation. The abnormal appearance of the Schumann-Runge continuum can be explained by either the variation of the electronic dipole moment with internuclear separation or the interaction of two electronic states at region corresponding to the short wave length side of the continuum.
