The raman spectra of organic compounds: Aniline

An intense Raman spectrum of aniline has yielded thirty-nine lines. They are: 234 (4,.71), 280 (0, D), 330 (0, D), 387 (4, 63), 408(1), 532 (5,.62), 619 (5,.62), 700(1,), 757 (3,.71), 775(0), 810 (8,.28), 830 (8,.30), 888 (0, P), 938 (1,P), 987 (0 ), 996 (10,.26), 1029 (5,.28), 1060 (0, ), 1110 (0 ), 1149 (3, .78), 1168 (2, .55), 1200(0, P), 1230 (0, P), 1272(4,.33), 1340 (1, D), 1388 (1, D), 1456 (2,.62), 1499 (2, P), 1538 (2, P), 1590 (2, D), 1601 (10,.69), 1612 (2, P), 2922 (2, P), 3020 (0, D), 3046 (10,.53), 3066 (4, P), 3190 (1, D), 3362 (3, P), and 3423 (2, D). Thirty of these are assigned to the benzene ring by comparing these frequencies with those of benzene and its monosubstituted derivatives. 3362 (3 P), 3423 (3 D,) and 1538 (2 P) are assigned to the NH2 group and 830 (8, .30) and 408 (1) to the C–N linkage.
