Abstract

Three new electronic transitions of CaS have been observed in the blue region of the spectrum. The vibrational bands in these transitions span thousands of cm-1 owing to a large change in geometry. Approximately 1000 cm-1 portion of the spectrum containing these bands has been recorded at high resolution by dye laser excitation spectroscopy and analyzed. The new states all have OMEGA = 1, and are tentatively labeled G (1)PI, F (1)PI, and f(3)PI. Spectroscopic constants have been generated for all three upper states and for the X (1)SIGMA+ state from a fit to 4340 individual lines. These constants have been used to generate potential curves and Franck-Condon factors.
