Cresyl violet perchlorate |
|
| The chemical structure of Cresyl violet perchlorate 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 Cresyl violet perchlorate dissolved in ethanol. 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]. Cresyl violet perchlorate has a molar extinction coefficient of 83,000 M-1cm-1 at 603 nm [R. R. Birge, "Kodak Laser Dyes," 1987].

Fluorescence
This is the fluorescence emission spectrum of Cresyl violet perchlorate dissolved in ethanol. The spectrum was taken by R. A. Fuh on summer, 95 using an excitation wavelength of 540 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 0.54 [D. Magde, J. H. Brannon, T. L. Cremers, and J. Olmsted,ŬIII, "Absolute luminescence yield of cresyl violet. A standard for the red.," J. Phys. Chem., 83, 696-699, 1979]. |
