EFFECTIVE ROTATION AND FINE-STRUCTURE HAMILTONIANS OF SYMMETRIC TOP MOLECULES IN DEGENERATE VIBRONIC STATES
MetadataShow full item record
Publisher:Ohio State University
Effective Hamiltonians, both first and second order, for rotation, spin-rotation and electron dipolar spin-spin interactions of a symmetric top molecule in a doubly degenerate vibronic state have been obtained group theoretically by the irreducible tensor method. It has further been shown that both first and second order Hamiltonians obey the same symmetry selection rules and thus have identical forms. A systematic procedure for obtaining the complete effective Hamiltonian as well as detailed results for the most frequently encountered symmetric top molecule point groups will be presented. Application of the theory to specific cases will be discussed.
