Raman spectra of benzene
WebbRaman spectra have been studied for the benzene and benzene- d6 crystals at various temperatures between 4·2° and 273°K. The low-frequency Raman bands due to lattice vibrations have been found to be extremely sharp at 4·2°K. Decrease of their frequencies with an increase of temperature is rather small in the temperature range below 77°K ... WebbThe Raman and IR spectra of 1,2-diaminobenzene and 4,5-dimethyl-1,2-diaminobenzene are reported and assignments of fundamental modes proposed. The surface-enhanced Raman spectra (SERS) of catechol, 1,2-diaminobenzene and 4,5-dimethyl-1,2-diaminobenzene on gold and silver colloids were obtained. FT-SERS of the three …
