1,6-Diphenylhexatriene |
|
| The chemical structure of 1,6-Diphenylhexatriene 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 1,6-Diphenylhexatriene dissolved in cyclohexane. It was measured by R. A. Fuh on 6/27/95 [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]. 1,6-Diphenylhexatriene has a molar extinction coefficient of 84,800 M-1cm-1 at 353.25 nm [I. B. Berlman, Academic Press, 1965]. Other fluorescence yields include 0.67 in methylcyclohexane [M. T. Allen and D. G. Whitten, "The photophysics and photochemistry of a,w-diphenylpolyene singlet states," Chem. Rev., 89, 1691-1702, 1989]. |

Fluorescence
This is the fluorescence emission spectrum of 1,6-Diphenylhexatriene dissolved in cyclohexane. The spectrum was taken by R. A. Fuh on 6/26/95 using an excitation wavelength of 336 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 0.78 [I. B. Berlman, Academic Press, 1965]. |
