cis-Stilbene This page summarizes the optical absorption and emission data of cis-Stilbene 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.


This optical absorption measurement of cis-Stilbene were made by M. Taniguchi on 10-27-2004 using a HP 8453. The absorption values were collected using a spectral bandwidth of 1.0 nm.

These measurements were scaled to make the molar extinction coefficient match the value of 36,230cm-1/M at 276.0nm (Kvaran, 2000).

No emission spectrum was provided owing to the expected low quantum yield.
