Molecular parameters for the band systems A, B-X of AuH and A-X of AuD

Abstract

Franck-Condon factors (vibrational transition probabilities) and r-centroids have been evaluated by a numerical integration procedure for the bands of A 0 +g − X 1 Σ + , B 0 +g − X 1 Σ + systems of AuH and A 0 + − X 1 Σ + system of AuD molecules using a suitable potential. The physical and astrophysical significances of our evaluated Franck-Condon factors and r-centroids have also been discussed, which would be helpful in the prediction of the presence of AuH and AuD molecules in various celestial bodies.
