Stains all |
|
| The chemical structure of Stains all 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 Stains all 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]. Stains all has a molar extinction coefficient of 96,500 M-1cm-1 at 575.5 nm [R. E. Kay, E. R. Walwick, and C. K. Gifford, "Spectral changes in a cationic dye due to interaction with macromolecules. I. Behavior of dye alone in solution and the effect of added macromolecules.," J. Phys. Chem., 68, 1896-1906, 1964]. A fluorescence spectrum was not recorded. |

Fluorescence
This is the fluorescence emission spectrum of Stains all dissolved in ethanol. The spectrum was taken by R. A. Fuh on 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 []. |
