For the first time, the high-frequency symmetric C-H stretching modes of chloroform and benzene are down-converted using the recently developed time-frequency-resolved interferometric coherent anti-Stokes Raman scattering with broad-band nontransform limited (noisy) light excitation method. As an application, chloroform-carbon tetrachloride, benzene-benzene-d(6) and benzene-acetone-d(6) dilution series are performed. Concentration-dependent Raman frequencies and vibrational dephasing rate constants are observed by this new technique.
