The vibrational spectra of the batho and lumi intermediates in the room-temperature rhodopsin photo-reaction are measured by picosecond time-resolved coherent anti-Stokes Raman spectroscopy (PTR/CARS). The instrumental principles underlying PTR/ CARS together with the advantages of PTR/CARS applications in protein reactions are discussed.

The ultrafast molecular vibrational dynamics in PMMA sheets is studied by femtosecond time-resolved coherent anti-Stokes Raman spectroscopy at room temperature. The C – H stretch modes at 2870 cm-1 and 3008 cm-1 in PMMA sheets are excited and detected. The coherence relaxation times and beat wavenumbers of the Raman modes are obtained.
