| Abstract: | The rotational dependence of Franck-Condon factors has been computed for selected bands of CN, CaH, C2, NH, TiO, MgH and CH using Morse-Pekeris eigenfunctions. Some bands show a rotational dependence which may be significant for the determination of rotational temperatures and abundances of elements and isotopes, and for opacity distribution function (“giant line]rd) calculations. The predicted rotational dependence for the (0, 1) band of the CH 4300 Å system is supported by an analysis of observed solar intensities. |
