Rocket Radiation Handbook, Volume 2. Model Equations for Photon Emission Rates and Absorption Cross-Sections
Abstract
A review is given of model equations for the calculation of photon emission and absorption cross-sections and rate constants for gaseous molecules in bound-bound transitions. Approximate expressions for electronic, vibrational, and rotational transitions are discussed and a generalized line- and band-broadening formulation is employed which allows explicit calculation of cross-sections and rates at any gas temperature and pressure as a function of photon frequency. A novel feature presented is the use of generalized broadening functions applicable to both lines and bands. These functions have often been treated unsatisfactorily or incompletely. With the first four chapters devoted mostly to a discussion of theoretical equations, the final chapter presents several explicit worked-out examples such as the absorption and stimulated emission cross-section of CO2 as a function of pressure, temperature, and gas composition.
