This page summarizes the optical absorption and emission data of TBP-beta-octa(COOBu)-Zn 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 TBP-beta-octa(COOBu)-Zn were made by O. Finikova on 10-16-2004 using a PerkinElmer Lambda 35.
These measurements were scaled to make the molar extinction coefficient match the value of 460,000cm-1/M at 452.0nm (Finikova, 2004).

Fluorescence
The fluorescence emission spectrum of TBP-beta-octa(COOBu)-Zn dissolved in DMF. The quantum yield of this molecule is 0.2 (Finikova, 2004). This spectrum was collected by on 10-24-2004 using a Fluorolog-2,R2658P.
