7-Benzylamino-4-nitrobenz-2-oxa-1,3-diazole This page summarizes the optical absorption and emission data of 7-Benzylamino-4-nitrobenz-2-oxa-1,3-diazole that is available in the PhotochemCAD package, version 2.1a (Du 1998, Dixon 2005). I reworked their data to produce these interactive graphs and to provide direct links to text files containing the raw and manipulated data. Although I have tried to be careful, I may have introduced some errors; the cautious user is advised to compare these results with the original sources.

You can resize any of the graphs by clicking and dragging a rectangle. If you hover the mouse over the graph, you will see a pop-up showing the coordinates. One of the icons in the upper right corner will let you export the graph in other formats.

Absorption

This optical absorption measurement of 7-Benzylamino-4-nitrobenz-2-oxa-1,3-diazole were made by R.-C. A. Fuh in the summer of 1995 using a Cary 3. The absorption values were collected using a spectral bandwidth of 1.0 nm, a signal averaging time of 0.133 sec, a data interval of 0.25 nm, and a scan rate of 112.5 nm/min.

These measurements were scaled to make the molar extinction coefficient match the value of 19,700cm-1/M at 460.5nm (Kenner, 1971).
