The Franck-Condon (FC) factors and r-centroids for the bands systemC 1 Σ + → X 1 Σ + of AlD and E 2 Π → X 2 Σ + of CaH have been evaluated by means of a reliable numerical integration procedure by using a suitable potential. The dissociation energy, D e, for the electronic ground states of AlD and CaH have been estimated by the curve fitting method to the RKRV experimental potential curve turning out to be 3.01 eV and 2.32 eV, respectively.
