 Meeting ID: 815 1723 8660  Passcode: 551308The presentation will start with 
a brief historical introduction to coherent Raman spectroscopy with 
particular emphasis on the physical basis of the scattering. Then it will be 
shown that a few significant findings of his former pioneering results of 
applications of the method on photoactive proteins got support from recent 
time-resolved X-ray diffraction measurements. The tasks needed to get 
reliable measurements and the necessary data processing of coherent Raman 
spectra will be discussed. His recent recognition of the usefulness of 
3-color two-beam coherent Raman scattering to measure low-frequency 
vibrational spectra will be detailed. The lecture will describe the necessary 
steps to apply the method to measure low-frequency phonon spectra of 
crystalline samples and present the first results on unique 
crystals. Minden érdeklődőt szívesen látunk! - Everyone is welcome to
