Abstract

Molecules in gas phase are randomly oriented within the laboratory frame of reference. When interacting with a linearly polarised laser field, the response of the molecular ensemble is thus an average over all orientations of the molecule with respect to the laser polarisation. This makes it impossible to resolve the effect of the molecular structure on the studied laser induced processes. In this chapter laser induced impulsive molecular alignment is presented as a technique to study laser-molecule interactions in the molecular frame.
