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 5,10-Diaryl Cu-oxochlorin 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 174,000cm-1/M at 419.0nm (Taniguchi, 2002).
