Oxazine 170 |
|
| The chemical structure of Oxazine 170 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 Oxazine 170 dissolved in methanol. 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]. Oxazine 170 has a molar extinction coefficient of 83,000 M-1cm-1 at 613.3 nm [R. R. Birge, "Kodak Laser Dyes," 1987].

Fluorescence
This is the fluorescence emission spectrum of Oxazine 170 dissolved in methanol. The spectrum was taken by R. A. Fuh on 6/24/97 using an excitation wavelength of 550 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 0.63 [R. Sens and K. H. Drexhage, "Fluorescence quantum yield of oxazine and carbazine laser dyes.," J. Luminesc., 24, 709-712, 1981]. |
