Ground-state reduced potential curves (RPC) of non-metallic first- and second-row hydrides

Abstract

Ground-state internuclear potentials of first- and second-row non-metallic hydrides, obtained from measured spectra by the RKR method or determined by ab initio calculations, are analysed with the use of the reduced potential curve (RPC) method. The rules of the RPC scheme reported before are found to hold in this group of chemically related molecules within the limits of the accuracy of the potentials (and the data) available. An interesting anomaly is observed.
