The effects of different linear polarization schemes on the noisy light‐based coherent anti‐Stokes Raman scattering [I (2) CARS] signal were investigated. It was found that certain polarization schemes can selectively shut down the contributions from terms represented by various factorized time correlation (FTC) diagrams to the I (2) CARS spectrogram. FTC diagram analysis was used in conjunction with the symmetry properties of the hyperpolarizability to provide a theoretical understanding of this phenomenon and serve as the basis for simulation of the I (2) CARS spectrogram. Striking agreement is seen between the simulations and the experimental results for benzene and several methylated benzene derivatives. Copyright © 2005 John Wiley & Sons, Ltd.
