The large class of polar molecules is interesting for controlled
studies with new light sources. The permanent dipole of the molecule
allows it to be oriented in space with the molecular axes being fixed
with respect to the laboratory fixed frame. In the talk, I will
discuss molecular frame photoelectron angular distributions, and high-
order harmonic spectra obtained from polar molecules. In the end of
the talk, I will discuss how the presence of a permanent dipole
affects time-resolved measurements on the attosecond timescale.
