Abstract
The absorption spectrum of CaH in the region 6 130-7 125 Å has been generated using a King furnace. The spectrum was recorded photographically in a 10.685 m concave grating spectrograph. Ten bands belonging to the A 2Π-X 2Σ and B 2Σ-X 2Σ systems have been rotationally analyzed. Perturbations between the two excited states have been observed. Computer methods have been used to calculate term values and to evaluate molecular constants.Keywords
