Abstract.The recently developed STIRAP-technique (J. Chem. Phys. 92, 5363 (t990)) is applied to efficient population transfer and alignment of metastable Ne* atoms. Alignment parameters in the range -0.3 > Ao 2 > --1.0 are observed. The degree of alignment can be controlled by changing the angle between the field vectors of the linearly polarized pump-and Stokes-lasers. The transfer efficiency depends also on this angle. The results of numerical calculations agree satisfactorily with the experimental data.

“…There are other laser methods that have been employed to produce state-selected molecules, e.g. chemical laser, Franck-Condon and stimulated Raman pumping (see Whitehead 1991 for details). These can be expected to be applied to the preparation of state-selected free radicals in the future.…”

“…The applicability of laser-induced fluorescence is limited to radicals having a suitable electronically excited state which can be accessed by the laser and which does not have significant non-radiative decay rates due to processes such as predissociation which will reduce the amount of fluorescence. The analysis of laser-induced fluorescence spectra can be complicated by the effects of laser saturation and polarization which are well understood and can be accounted for (see Whitehead (1991) for references).…”

In this review, the production and detection of a wide range of unstable free-radical species under molecular beam conditions are described. The use of such molecular beam methods to study the photodissociation and inelastic and reactive scattering of free radicals in recent years is reviewed. A selection of the many experiments on the photodissociation of radicals that have been performed recently using molecular beam conditions is described to illustrate the range and scope of such experiments. For the comparatively smaller fields of free-radical inelastic and reactive scattering studied using molecular beam techniques, a comprehensive review is presented. In all cases, the experimental results are interpreted and discussed with reference to recent related theoretical calculations on the electronic structure and dynamics for the systems. A particular aim is to illustrate how the observed features of the experiments are related to information on the topography of and the couplings between the appropriate potential energy surfaces and the associated dynamics.

Quasiclassical trajectory method (QCT) has been used to investigate the effect of vibrational excitation on the relative cross section for the reaction Cl+Na2(v″). The calculated results are in good agreement with the experimental data, which show the increase of the cross section with increasing vibrational excitation. Furthermore, the spectroscopy of transition state in this reaction has been predicted out using QCT method based on LEPS potential energy surface.
