Aromatic overtones: In infrared spectroscopy, a series of small peaks (usually three or four) typically found in the ~2000 cm-1 to ~1700 cm-1 range. The structure of benzene is fully determined once the interatomic distances rcc and rCH are obtained from experimental data. Here the P and R branches of the n4 parallel band of C6H6 (674 cm-1) and of C6D6 (496 cm-1) are … This infrared spectroscopy experiment allows the determination of rcc and rCH from the rotational analysis of an infrared active band of C6H6 and one of its isotopomers, C6D6.
