Abstract
Broadband femtosecond time-resolved coherent anti-Stokes Raman scattering ((TR-CARS)) is utilized to investigate the wave-packet dynamics of Cresyl Violet (CV670) dye molecules in ethanol solvent at room temperature. An interesting behavior of wave-packet dynamics phenomena is observed and discussed for the first time, and several unknown Raman vibrational modes with frequency differences of 32â¯cmâ1, 38â¯cmâ1, 45â¯cmâ1, 50â¯cmâ1, 55â¯cmâ1, 65â¯cmâ1, 80â¯cmâ1, 95â¯cmâ1 and 101â¯cmâ1 are excited and obtained at the same time. This work makes possible high efficiency in the structure investigation as well as dynamics of intra-molecular processes by broadband femtosecond (TR-CARS) spectroscopy with fast Fourier transformation (FFT) analysis means.
