โœฆ Synopsis


An attempt to investigate the vibrational bands near the origin of the E band of SO* has been made in a supersonic jet experiment. Several cold vibrational bands have been identified within the 32850-32880 cm-' region and their fluorescence spectra have been selectively excited and measured. A hot band activity at * 32872 cm-' was found to persist at low rotational temperatures, which caused the Franck-Condon intensity pattern of the E band's fluorescence spectrum to vary when measured under slightly different cooling conditions. The band's upper levels were not all found to have the same vibronic symmetry as that of the E band.
