Molecular Beam Laser Spectroscopy

Henning Meyer

Our research program is centered around the experimental study of the interactions in molecular clusters. The interest in such systems is motivated largely by the prospect of developing a detailed understanding of bulk matter through the access to direct quantum specific information on finite sized molecular clusters. Dimers are of particular interest as the first step towards describing bulk material at a molecular level. Their structure and dynamics can be described in terms of a multidimensional potential energy surface (PES) which provides the basis for a great variety of active research areas like molecular modelling of bio-molecules and the influence due to solvent effects. It is also the basis for the theoretical description of bimolecular reactions and energy transfer which are essential to understanding and modelling of such diverse processes like combustion, atmospheric warming and pollution.

As part of the PHYS 8990 rotation, the incoming graduate student will be exposed to different techniques employed in our research: 

  1. Molecular beam laser spectroscopy of clusters in the ultraviolet and infrared.
  2. Laser spectroscopic detection of molecular products in molecular beam scattering experiments. 

The theoretical background of these experiments is soundly based on non-relativistic quantum mechanics either through the bound or the continuum states of the cluster under investigation. Although the main emphasis is on experimental research, theoretical work on our own or in collaboration with theory groups represents another important aspect of this research,
