| The chemical structure of Magnesium octaethylporphyrin (MgOEP) 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 Magnesium octaethylporphyrin (MgOEP) dissolved in toluene. It was measured by R. A. Fuh on 6/25/97 [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]. Magnesium octaethylporphyrin (MgOEP) has a molar extinction coefficient of 408,300 M-1cm-1 at 409.75 nm [E. Zass, H. P. Isenring, R. Etter, and A. Eschenmoser, "Der Einbau van Magnesium in Liganden der Chlorophyll-Reihe mit (2,6-di-t-butyl-4-methylphenoxy)magnesiumjodid," Helv. Chim. Acta, 63, 1048-1067, 1980].

Fluorescence
This is the fluorescence emission spectrum of Magnesium octaethylporphyrin (MgOEP) dissolved in toluene. The spectrum was taken by R. A. Fuh on 6/25/97 using an excitation wavelength of 545 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 0.15 []. |
