Bilirubin |
|
| The chemical structure of Bilirubin 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 Bilirubin dissolved in chloroform. 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]. Bilirubin has a molar extinction coefficient of 55,000 M-1cm-1 at 450.8 nm [G. Agati and F. Fusi, "New trends in photobiology recent advances in bilirubin photophysics," J. Photochem. Photobiol., 7, 1-14, 1990]. A fluorescence quantum yield of 0.1 was observed in an EPA glass at 77 K [A. Cu, G. G. Bellah, and D. A. Lightner, "On the fluorescence of bilirubin," J. Am. Chem. Soc., 97, 2579-2580, 1975]. |
