Resumo

The use of near-IR FT-Raman spectroscopy to obtain resonance-free spectra of a substituted azobenzene dye has been investigated. Although the incident laser wavelength was detuned by ∼500 nm from resonance with the dye absorption maximum, bands due to the dye chromophore still dominated the spectrum even though strongly-scattering groups (methacrylate, sulphone) were also present in the molecule. These results are similar to those obtained by other workers in studies on chromophoric proteins.
