Abstract
Resonance Raman spectra are reported for several biologically important nitroanilines and nitrophenols. The data provide new insight into intramolecular interactions in highly conjugated nitroaromatics. In certain ortho substituted compounds the data provide evidence for structural changes in going from the ground to the excited electronic state, or states, probed by the resonance Raman experiment. In each compound several Raman bands show variation of intensity with excitation wavelength. For N‐methyl‐o‐ nitroaniline excitation profiles for some isolated bands appear to peak at the maximum of the electronic absorption band at 442.0 nm. Experimental intensity profiles are compared to the presently available theories.Keywords
