Lucifer yellow CH |
|
| The chemical structure of Lucifer yellow CH 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 Lucifer yellow CH dissolved in water. It was measured by R. A. Fuh on summer, 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]. Lucifer yellow CH has a molar extinction coefficient of 24,200 M-1cm-1 at 279.75 nm [W. W. Stewart, "Synthesis of 3,6-disulfonated 4-aminonapthalimides.," J. Am. Chem. Soc., 103, 7615-7620, 1981].

Fluorescence
This is the fluorescence emission spectrum of Lucifer yellow CH dissolved in water. The spectrum was taken by R. A. Fuh on summer, 95 using an excitation wavelength of 380 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 0.21 [W. W. Stewart, "Synthesis of 3,6-disulfonated 4-aminonapthalimides.," J. Am. Chem. Soc., 103, 7615-7620, 1981]. |
