Extension of the Molecular Quantum Defect Orbital Methodology to the Calculation of Intensities and Lifetimes for Vibronic Transitions within Electronic Rydberg Series of NO

摘要

Expressions relating explicitly the radiative lifetimes of vibronic states to the electronic transition moment and the absorption oscillator strengths for spin-allowed transitions have been developed for the first time within the molecular quantum defect orbital(MQDO)methodology.Application to the intensities of the gamma(A~2DELTA~+ <-X~2II),sigma(D~2DELTA~+ <-X~2R),and(D~2DELTA~+ <-A~2DELTA~+)bands of NO,which are known to be of relevance in atmospheric studies,has been made.The MQDO results are in excellent accord with the measurements available in the literature.
