15.4: Spectral Characteristics of the Benzene Ring
Arenes have absorption bands in the 650-900 cm −1 region due to bending of the C–H bond out of the plane of the ring. The exact placement of these absorptions can indicate the pattern of substitution on a benzene ring.

Absorption spectra of benzene with different spectral resolution
This paper presents a deep-UV absorption spectrophotometer coupled with a micro gas-chromatography (μGC) for the detection of benzene, toluene, ethylbenzene and xylenes (BTEX).
Absorption [Benzene] - AAT Bioquest
Benzene is a fluorescent compound with an excitation peak at 255 nm and an emission peak at 278 nm. AAT Bioquest's interactive Spectrum Viewer is a powerful tool for analysis and comparison of the spectra of common compounds used in absorbance and fluorescence formats. The Spectrum Viewer is set to fluorescent mode by default.

This page summarizes the optical absorption and emission data of Benzene that is available in the PhotochemCAD package, version 2.1a (Du 1998, Dixon 2005). I reworked their data to produce these interactive graphs and to provide direct links to text files containing the raw and manipulated data.

2009年6月1日 · The UV absorption spectrum of benzene is attributed to the S 1 ( 1 B 2u )←S 0 ( 1 A 1g) electronic transition. It is the lowest singlet system of the molecule and is electronically forbidden but vibrationally induced. The dominant vibronic progression is designated 6 0 1 and involves ν1 the symmetrical ring-breathing vibration.
