The equilibrium geometry and hydrogen-bonding energy of the heterobiialide ion FHCl-have been calculated by ab initio SCF and hIRD CI methods using an A0 basis set of near Hartree-Fock quality. In the most stable (linear) conformation of this ion, the equilibrium F-Cl/F-H distances are predicted to

β¦ Synopsis
The electroluc structure of the vanadyl 10" has been calculated m fields of monopoles and dipoles usmg RHF. CI pnd MC SCF methods. The MC SCF calculations use the complete active space formahsm The results show a strong pticipauon of the vanadium 3d orbllals m both o and * bondmg The 3d populauon is found 10 be between 23 ar.d 2 9 -much higher than the formal d' cbaractenzatron. The system becomes more zonk m the MC SCF d-ption, and there 1s a sigmfican~ mung of conligurallons. in wbch excltauons involvmg e to e* transitions are the most Important. The electromc s.Wuclures of some of the exclkd stiles have been calculated.

Potential curves for the X 2~g, A 2~u, B 2 C: and C 2x; electronic states of BO2 were calculated at ab initio SCF RHF and confiiuration Interaction (CI) level. The results obtained are consistent with a linear molecular model for all states considered. The calculated structural parameters and transi
## Abstract An __ab initio__ SCF calculation of 42 points of the energy hypersurface of the fluoronium ion is presented using a contracted F(5__s__/3p), H(2s) gaussian basis set. In its equilibrium structure a bond length of 1.812 a.u. and a HFH bond angle of 127.2Β° are predicted. The calculated vi
The electrostatic potential is usually evaluated by putting a test charge at several points on an appropriate molecular surface. The polarization effect is an indispensable long-range interaction as well as the electrostatic interaction. To evaluate the polarization effect, it is necessary to relax
The ionized states of [CO~(~~-C~H,)~(CO)~] and [Co,($-C,H,),(NO),] are investigated by a CI method which allows for electron reorganization, positive hole localization, and includes part of the correlation energy. Qualitative bonding schemes and the photoelectron spectra are discussed in terms of th
