Abstract

We have preformed femtosecond time-resolved coherent anti-Stokes Raman spectroscopy (CARS) to study the vibrational dynamics in polymethylmethacrylate (PMMA) film. We measured the coherent vibrational relaxation rates of CH2 symmetric and CH2 anti-symmetric stretch modes (at 2750 cm1 and 2950 cm1) and observed the CARS signal beats between CH2 stretch modes in PMMA. Numerical fitting involving two contributions provided the coherent vibrational relaxation time for each stretch mode. The coherent vibrational relaxation of antisymmetric mode in PMMA was found much faster than that of symmetric mode.
