Naphthalene |
|
| The chemical structure of Naphthalene 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 Naphthalene dissolved in cyclohexane. It was measured by R. A. Fuh on 69/95 [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]. Naphthalene has a molar extinction coefficient of 6,000 M-1cm-1 at 275 nm [I. B. Berlman, Handbook of Fluorescence Spectra of Aromatic Molecules, Academic Press, 1971].

Fluorescence
This is the fluorescence emission spectrum of Naphthalene dissolved in cyclohexane. The spectrum was taken by R. A. Fuh on 69/95 using an excitation wavelength of 270 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 0.23 [I. B. Berlman, Handbook of Fluorescence Spectra of Aromatic Molecules, Academic Press, 1971]. |
