Vibration Rotation

Theoretical vibration–rotation coefficients for tritiated and deuterated [Formula: see text] are reported for Carney and Porter's ab initio electronic CI potential energy surface. In the calculation of coefficients connecting the zero-point and fundamental states of vibration, accurate vibrational CI wave functions, consisting of 220 configuration functions, were used.

Electronic Wave Functions

For the [Formula: see text] ion, the geometries and energies of several minima, and barriers between these, have been calculated from correlated self-consistent electron pair (SCEP) and coupled electron pair (CEPA) electronic wave functions. The spectroscopic and kinetic implications of the potential energy surface are discussed in terms of its molecular symmetry group.

Field Perspective

The potential energy surface of 252 Cf has been computed within the Hartree-Fock-Bogolubov theory with the D1S Gogny force. The shape evolution of the nucleus during the fission process have been studied. Quadrupole, octupole and hexadecapole deformations have been taken into consideration.

Triatomic Molecules

We have proposed a new method to calculate low lying eigenstates of Hamiltonian operator for triatomic molecules. The method is a grid method based on continuously pumping flux onto the potential energy surface and gives the wave function overlapping with prechosen energy of interest. This energy may correspond to a bound state, a resonance or a continuum state. We have calculated several low lying bound state energies and corresponding bound state wave functions for HOCl with HO bond fixed at its equilibrium value.
