Abstract
The blue-green (B2∊ X2∊) and orange (A2∊ –X2∊) systems of yttrium oxide have been shock excited at temperatures of about 4000°K and photographed at high dispersion (∼ 1.2Å/mm) in the first order of a 21 ft. grating spectrograph. The high dispersion shock excited spectra were recorded using multiple exposures and latensification of extremely high speed film. Over 50 new bands have been observed and assigned to specific vibrational transitions for the systems. New molecular constants have been derived from the A, B and X states. Provisional calculations have been made of Franck-Condon factors and r-centroids for the systems appropriate to new constants.Keywords
