Hematin |
|
| The chemical structure of Hematin 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 Hematin dissolved in acetic acid. It was measured by Junzhong Li on 12/11/97 [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]. Hematin has a molar extinction coefficient of 85,000 M-1cm-1 at 386 nm [J. Keilin, "Reactions of free haematins and haeomoproteins with nitric oxide and certain other substances.," Biochem. J., 59, 571-579, 1955]. No fluorescence was observed in acetic acid. |
