Polarization‐sensitive resonance coherent anti‐Stokes Raman scattering spectroscopy of magnesium octaethylporphine (MgOEP) in dichloromethane is reported. The measurements were performed in resonance with the Q ‐band electronic absorption where linear resonance Raman spectroscopic measurements were foiled by excessive fluorescence. A high porphyrin concentration allowed direct identification of the different vibrational mode symmetries. Complementary vibrational information was obtained from B ‐band resonance Raman spectra. MgOEP was found to be structurally similar to nickel octaethylporphine, but with an expanded porphyrin core. Copyright © 1999 John Wiley & Sons, Ltd.
