This page summarizes the optical absorption and emission data of 5,10-Diaryl Cu-chlorin 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 5,10-Diaryl Cu-chlorin were made by M. Taniguchi on 10-02-2004 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 162,000cm-1/M at 408.0nm (Taniguchi, 2002).

Fluorescence
The fluorescence emission spectrum of 5,10-Diaryl Cu-chlorin dissolved in toluene. The quantum yield of this molecule is 0. Due to the expected low fluorescence yield, the value is set to 0.. This spectrum was collected by using a PTI 814.
