Description
Field-free alignment and orientation of molecules is an important prerequisite for many gas phase
imaging experiments. It allows to access information directly in the molecular frame and extract
observables such as internuclear distances, angles and the electronic density through a
measurement of the photoelectron angular distribution.
We present new experimental results and simulations on strongly field-free aligned molecules,
ranging from linear to complex asymmetric rotor molecules. Additionally, photoelectron
momentum distributions of strongly aligned OCS molecules, recorded experimentally at different
angles between the laser polarization axis and the molecular axis will be presented. The
photoelectron angular distributions display large modification with the molecular axis distribution,
both at low and high kinetic energies, which encode the molecular structure and electronic
density of the molecule. A discussion of the experimental results will be presented.
