Transient Scattering by Vibrational Coherence and Gratings in a Multi-Resonant Four Level System
Mixed molecular crystals offer a number of valuable spectroscopic features for studies of multilevel optical phenomena in solids. By doping a host crystal with a sterically compatible guest, one obtains in effect an oriented static gas. At partper-million concentrations, guest-guest interactions are negligible. Guest-host electronic interactions are also often weak and quite homogeneous.
