Oxazine 1 |
|
| The chemical structure of Oxazine 1 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 1 dissolved in methanol. It was measured by R. A. Fuh on 6/21/95 [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]. Oxazine 1 has a molar extinction coefficient of 123,000 M-1cm-1 at 642.5 nm [R. R. Birge, "Kodak Laser Dyes," 1987]. The fluorescence yield increases to 0.19 in ethylene glycol [R. Sens and K. H. Drexhage, "Fluorescence quantum yield of oxazine and carbazine laser dyes.," J. Luminesc., 24, 709-712, 1981]. |

Fluorescence
This is the fluorescence emission spectrum of Oxazine 1 dissolved in ethanol. The spectrum was taken by R. A. Fuh on 6/21/95 using an excitation wavelength of 590 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 0.11 [R. Sens and K. H. Drexhage, "Fluorescence quantum yield of oxazine and carbazine laser dyes.," J. Luminesc., 24, 709-712, 1981]. |
