Abstract : Optical spectroscopy has been used to study a number of collision processes. Quantitative spectroscopic measurements of both wavelength and intensity made it possible to determine some new mechanisms of energy exchange, and, in some cases, to obtain some new collision cross sections. In the gas phase, rate coefficients have been measured for several helium energy transfer collisions, conditions have been established for mechanisms producing excited CN, and collision broadening of metal atoms and of OH in flames has been studied. In the condensed phase, scattering of monochromatic radiation from liquids and simple solids produced information about energy exchange with phonons, molecular rotation, and vibration. (Author)
