Good College of Information Science and Systems Engineering, University of Arkansas at Little Rock, 2801 South University Avenue, Little Rock, AR 72204-1099, USA Abstract: The science of chemistry underlies all of our work in the environmental area and in the new technologies exemplified by materials science and molecular physics. For these areas to progress, chemistry must continue to be a

November 1971) Occupation number representation and operator-technique are used in the calculation of harmonic oscillator matrixelements for one and two centres and for equal and different frequencies. The potentials treated are generalized Gauss-potentials of the f o rm pk xl e x p { a x 2 } , xk pl e x p { a p2}, and pk xl e x p { o x p} which by application of an operator identity could be reduced to the same form. Applications in nuclear and molecular physics, in molecular spectroscopy and in quantum chemistry are discussed briefly. 1. Introduction I n t w o
