Abstract:

Four new violet degraded bands of CaH have been observed in absorption in the region 2 900 to 3 200 A by heating calcium and hydrogen to 1 200-1 400C. Rotational analysis indicates that the bands belong to two closelying systems K doublet sigma -X doublet sigma and L doublet Pi - X doublet sigma which are separated by 50cm for the 0-0 bands. The rotational levels for the excited states approximate to Hunds case d coupling with L 1. A Hamiltonian matrix has been constructed for the two states and constants for the unperturbed states evaluated. Modified author abstract
