FOURIER TRANSFORM INFRARED EMISSION SPECTRA OF CaH AND SrH

Abstract

The vibration-rotation spectra of gaseous CaH and SrH have been recorded in emission using a furnace-discharge source. Ca and Sr vapor were produced at $780^{\circ}C$ and $850^{\circ}C$, respectively, and reacted with a few torr of hydrogen gas under a 3 kV / 333 mA discharge to produce the metal hydrides. The fundamental and first three hot bands, $v=1-0$ to $v=4-3$, in the ${^{2}}\Sigma^{+}$ ground electronic state of each molecule were observed. The analysis of the data is in progress and will be presented.
