These spectra are for liquid-nitrogen temperature, the solvents being n-pentane, n-hexane, n-heptane, and n-octane. Each has a vibrational structure, the vibrational frequencies being independent of the solvent. Acenaphthene in pentane and octane gives 12 peaks corresponding to vibrational frequencies of 414, 630, 1152, 1409, and 1604 cm, the last two being the strongest. Diphenyl in pentane and heptane gives gives 21 peaks; the strongest vibrations are 1610 and 1275 cm, others being 1003, 320, and 735 cm. Carbazole in pentane and hexane gives 15 peaks that fit the frequencies 750, 852, 1141, 1305, 1477, and 1605 cm, the first and last being the strongest. [ABSTRACT FROM AUTHOR] |
