Tetraphenylsapphyrin This page summarizes the optical absorption and emission data of Tetraphenylsapphyrin 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 Tetraphenylsapphyrin were made by M. Taniguchi on 10-04-2004 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 74,900cm-1/M at 493.0nm (Chmielewski, 1995).
