Investigation of coherence transfer between “CH3” and “CH2” groups in ethanol with time-resolved multiplex CARS technique

The coherence transfer between stretching vibration modes of C–H bonds in the ethanol is detected by time-resolved multiplex CARS technique and it occurs via “through-bond transfer” pathway. The time scale and velocity of coherence transfer are estimated at 90 fs and 1670 m/s. Moreover, coherence transfer process requires vibrational modes of acceptor and donor are different.
