Malachite Green |
|
| The chemical structure of Malachite Green 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 Malachite Green 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]. Malachite Green has a molar extinction coefficient of 148,900 M-1cm-1 at 616.5 nm [F. J. Green, The Sigma-Aldrich Handbook of Stains, Dyes and Indicators, Aldrich Chem. Comp., 1990]. A fluorescence spectrum was not recorded since most arylmethine dyes have such low emission in fluid solvents. |
