THE INTERPRETATION OF INTENSITY MEASUREMENTS OF DIATOMIC MOLECULAR BAND $SYSTEMS^{*}$

Abstract

The dependence of molecular band intensities upon source conditions and molecular constants will be discussed. In particular a method whereby the variation of electronic transition moment with internuclear separation may be determined from band intensities will be described. This method requires a knowledge of Franck-Condon Factors and r-centroids of the bands, and methods of determining these will be outlined. Experimental and theoretical results so far obtained for a number of band systems will be presented.
