Ultrafast vibrational dephasing dynamics of 9,10-bis(phenylethynyl) anthracene thin film revealed by femtosecond coherent anti-stokes Raman scattering

Ultrafast vibrational dephasing dynamics of 9,10-bis(phenylethynyl)anthracene (BPEA) thin films were revealed by femtosecond coherent anti-stokes Raman scattering spectroscopy (fs-CARS). Dephasing times ( T 2 ) of 2.60, 2.98, 3.72, and 1.64 ps were acquired at 1213, 1300, 1400, and 1478 cm −1 vibrat...
