Abstract
Spectroscopic studies with linearly or circularly polarized light
of partially aligned molecular samples can provide two kinds of
important information. One type of information is the molecular ·
alignment; the complete molecular orientation distribution function
can not be found, but its essential properties can be determined,
and these frequently enable a detailed interpretation of the spectrum.
This leads to the other kind of information, which has to
do with the anisotropic molecular optical properties : transition
moments, MCD B-terms, Raman polarizability tensors, etc.
A survey of the field is given together with a short description
of the mathematical treatment of molecular orientation and
optical properties. The different spectroscopic methods are illustrated
by a number of examples based on absorption, magnetic
circular dichroism, and photoluminescence.
