Competition between autoionization and predissociation in the HCl and DCl molecules

摘要: Experimental photodissociation cross sections for HCl and DCl have been recently measured in the autoionization energy region. These are obtained from fluorescence excitation spectra of fragments visible [White et al., J. Chem. Phys. 87, 6553 (1987)] or VUV [Frohlich al. (to be published)] The peaks observed between 770–900 A do not appear same place as that photoionization sections. theoretical explanation this fact is proposed. Rydberg states with a A 2 Σ+ core predissociated due to spin–orbit interaction, by belonging series converging repulsive a 4 Π state HCl+ . Using an unified MQDT treatment predissociation processes, calculated compared experimental results. It concluded which symmetry ...
