Semiempirical Analysis of Perturbations in the Triplet 3s,3d-Complex of Terms of a Hydrogen Molecule: Comparison of Results Obtained by Optical and Photofragmentation Spectroscopy

摘要

Ratios of probabilities of spontaneous emission from rovibronic levels of the triplet 3s,3d-complex of terms to the predissociation c3 and repulsive b3 states of H2 are calculated from ratios of effective values of dipole moments that are obtained semiempirically from data of optical spectroscopy. The calculated values were found to be nearly three times greater than the experimental values available in the literature, which were determined from velocity spectra of atoms produced in laser-stimulated photofragmentation of a beam of high-velocity metastable hydrogen molecules. Possible reasons for this discrepancy are discussed.
