Comparison of potential energy curves for the ground states of SiH molecule with reduced potential energy curve

ABSTRACT

The diatomic SiH molecule is spectroscopically studied by many workers. The accurate ground state constants of this molecule derived from latest Fourier Transform spectroscopic analysis are used to construct the RKRV curves. The Hulbert-Hirschfelder, extended Rydberg and Zavitsas potential energy functions are used and are compared with their respective RKRV curves. The error curve is also studied. The Reduced Potential Energy Curve (RPC) of these molecules are also constructed. It was found that these curves obey the rules of RPC’s.
