Correction energy of water and hydrogen fluoride

We wish to study the correction energy of water and hydrogen fluoride (HF) using the recently developed canonical sequence method (CSM) which is a calculational cousin of the connected moments expansion (CMX) of Cioslowski. Comparisons are then made with other methods [for example, P.J. Knowles, Chem. Phys. Lett. 134 (1987) 512].
