Rotational wave packet imaging of molecules

Ultrafast laser pulse induced molecular alignment is a prerequisite for many investigations of dynamical processes in molecules. The basics of molecular alignment, its characterization and dissipation back to equilibrium in dense media will be the initial focus.
Molecular alignment being the outcome of rotational wave packets, the possibility of imaging rotational wavepackets in angular space and time using different pump-probe spectroscopic techniques will be taken up subsequently.
A general theoretical framework to perform such rotational mapping is derived and three specific spectroscopies, namely, Raman induced polarization spectroscopy, high harmonic generation and angle-resolved photoelectron spectroscopy, are numerically explored in the case of linear molecules.
