Recent Developments

A lifetimes technique that is readily applicable to neutral and singly ionised atoms of a wide range of elements, including the highly refractory elements, is reviewed. With this technique an atomic vapour of the element under study is generated by cathodic sputtering in a low pressure rare-gas discharge and fluorescence decay signals emitted by the vapour following pulsed laser excitation are recorded directly in a fast transient digitiser. Theoretical expressions are presented for the form of the time-resolved fluor~scence signal appropriate to the collisional environment of a rare-gas sputtering discharge. A summary is given of the atomic systems studied to date using this technique, and some new results for Sm and Ba are compared with recently reported results for these elements.

Double Resonance Spectroscopy

Spectroscopic and dynamical studies of the van der Waals complexes of benzene–Ar, benzene–N2 and benzene dimer in the electronically ground state (S0) have been performed by the use of stimulated Raman–UV optical double resonance spectroscopy. The vibrational frequency of mode 1 of the complexes and the decay rate constants of the 11 levels (∼993 cm-1) have been measured. The vibrational frequency shifts of mode 1 in S0 upon complex formation were less than 1 cm-1for all the complexes. On the other hand, the decay rate constant due to intramolecular vibrational redistribution and/or vibrational predissociation showed a drastic change. The decay rate constant of the 11 level of the benzene dimer was 2.4 × 107 s-1, while those of the benzene–Ar and benzene–N2 complexes were much smaller than 1 × 106 s-1. It was also found that the decay rate constant in S0 is much smaller than that in S1. For the benzene dimer, the depolarization ratio of Raman band of mode 1 was recalculated by taking into account of the anisotropy of the polarizability of benzene molecule. The comparison between the observed and calculated polarization ratio shows that the benzene dimer has the “T-shaped” structure which was proposed by the group of Felker.
