SCF excited states and transition probabilities of some neon-like and argon- like ions

: This is a collection of related, but independent, theoretical and experimental studies concerned with the electronic structure of atoms and molecules. Hartree-Fock of SCF wavefunctions are given for Neon-like and Argon- like ions, F2, N2, CO, BF, and NeH(+) and HeH(+) molecular ions. X-ray transition probabilities are also given for Neon-like and Argon-like ions and a number of molecular properties are given for F2, CO, BF. The octopole moment of methane is calculated. Mathematical expressions are given for certain generalizations of Laplace's expansion. The rotational-electronic interaction for the Rydberg states of diatomic molecules is examined as is the electric quadrupole and magnetic dipole radiation in linear molecules. Experimental studies are presented for some weak systems of N2 and certain Rydberg states of He2.
