MOLECULAR CONSTANTS FOR ALKALI HYDRIDES

Author Institution: Department of Physics, University of Illinois at Chicago CircleFrom the recent electronic spectral data, the quadratic, cubic, and quartic potential energy constants have been calculated for the alkali hydride molecules of NaH, KH, KD, RbH, RbD, and CsH for $A^{1}\Sigma^{+}$ and $X^{1}\Sigma^{+}$ states. By calculating the rotational constant $\alpha_{e}$, the applicability of the Morse potential function for these molecules is tested. Potential curves, Franck-Condon factors, and values of r-centroids will be presented in addition to the potential energy constants for these alkali hydride molecules
