摘要: The band intensities of Raman spectrum PTZ in the solid state show a clear dependence on laser excitation wavelength. Such behaviour, not observed when is obtained from solution, indicates that crystal molecular. orbital compound perturbed to some extent. · SO2 complex solution presents same pre-resonahce pattern as does PTZ, suggesting involved both cases. most enhanced modes are those ascribed aromatic ring vibrations, indicating an interaction through π molecular orbitals; it proposed acts π-donor toward basis pre-resonance SO2.
