“…3 Moreover, CARS gives access to vibrational coherences on the ground electronic surface, about which the existing information is convoluted in line shapes of frequency domain resonant Raman ͑RR͒ spectra. The very diverse aims pursued in this field may be illustrated with examples of applications in liquid phase dynamics, 16 studies of biomolecules in vivo and in vitro, 17 to carrier dynamics in solids, 18 band dynamics in superlattices, 19 to the interrogation of molecular solids, 20 to microscopy. There are, however, both practical and fundamental considerations in the choice of the measurement domain.…”
