The transform method has been used to investigate the CARS excitation profiles (CEPs) of a highly fluorescent cyanine dye including linear non‐Condon sources of scattering. It is demonstrated that the calculated predictions of the CEPs are in good agreement with the experimental data of the CARS excitation profile of the dye. The observed values of the linear non‐Condon activity parameters, C a , of three vibrational modes of 3,3′‐diethylthiacar‐bocyanine bromide were as large as 0.3. This suggests that linear non‐Condon electronic transition moments are important in the investigation of CEPs of cyanine dyes.
