Phenol |
|
| The chemical structure of Phenol is shown at the right. The absorption and fluorescence emission spectra are shown below. The structure, absorption, and fluorescence data were all obtained from the PhotochemCAD package by Jonathan Lindsey. This excellent program allows rapid comparison of spectra and enables one to do a variety of photochemically relevant calculations. |

Absorption
This is a graph of the molar extinction coefficient of Phenol dissolved in hexane. It was measured by R. A. Fuh on summer, 95 [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. Phenol has a molar extinction coefficient of 2,340 M-1cm-1 at 270.75 nm [I. B. Berlman, Handbook of Fluorescence Spectra of Aromatic Molecules, Academic Press, 1971].

Fluorescence
This is the fluorescence emission spectrum of Phenol dissolved in hexane. The spectrum was taken by R. A. Fuh on summer, 95 using an excitation wavelength of 260 nm [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. The quantum yield is 0.075 [G. Grabner, G. Kolhler, G. Marconi, S. Monti, and E. Venuti, "Photophysical properties of methylated phenols in nonpolar solvents," J. Phys. Chem., 94, 3609-3613, 1990]. |
