Coherent anti-Stokes Eaman spectroscopy provides distinct advantages due to its high efficiency, high resolution, suppression of back-ground fluorescence and coherent anti-Stokes character. An experimental arrangement employing two dye lasers pumped by a single nitrogen laser has been set up for CABS and the output signal is detected with photomultiplier and boxcar integrater. Spectra of benzene, toluene and a series of halogen substituted benzene derivatives ia the vicinity of 1000cm-1 have been measured.
