A coordinate representation for a polenlial energy surface is derived usmg the semiclassical hmil of the algebrax Hamihonian This provides a direct route rrom the observed ovenone spectrum IO a potential. The limilalions of this potenual are noted. Applicallons lo HCN. H,O. SO2 and 0, are reported.
A program has been developed in order to fit analytical power series expansions (Dunham, Simon-Parr-Finlan, Ogilvie and their exponential variants) and Padรฉ approximants to discrete ab initio potential energy surfaces of non-linear triatomic molecules. The program employs standard least-squares fitt
The rotated-Morse curve cubic spliie method developed previously is extended to bent triatomic molecules by usinS 25 cubic splmes. The Yates-Lester potential for bent Hs is shown to be accurately fitted over the entire raqe of the three internal coordinates, with a standard deviation of less than 1
