โœฆ Synopsis

The nbratlonal dephasmg of the methyl CH2 symmclnc stretch made III glycerol was duectly measured over an extendcd tcmpersture range usmg plmsecond cohercnr Raman pump and probe spectroscopy. The dephlsing time was found to mcrcasc dramatically a~ the tcmpcralure oi the supercooled hqmd ws lowered. T~s observation s altnbuted lo the u~creascd hydrogen bondrng with dccrcssmg temperature whch hmders the dephasmg of the CHz vibration by reducmg molecular

Femtosecond time-resolved coherent anti-Stokes Raman scattering has been observed for the C-N stretching vibration of alkanenitriles ( CnHrn+ t CN, n E l-17). The vibrational dephasing rates ( 1 / Fr ) observed for the neat alkanenitriles are proportional to the square root ofthe number of carbon at
