Optical molecular dephasing: principles of and probings by coherent laser spectroscopy

Coherent laser spectroscopy of large molecules is a new and challenging area of study. The strength of this type of optical spectroscopy is that it can probe important dynamical molecular processes that are not amenable to conventional methods such as absorption and emission spectroscopy. One such dynamical process is optical dephasing.
