This page summarizes the optical absorption and emission data of Crystal violet, 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.
This optical absorption measurement of Crystal violet, were made by R.-C. A. Fuh in the summer of 1995 using a Cary 3. The absorption values were collected using a spectral bandwidth of 1.0 nm, a signal averaging time of 0.133 sec, a data interval of 0.25 nm, and a scan rate of 112.5 nm/min.
These measurements were scaled to make the molar extinction coefficient match the value of 112,000cm-1/M at 509.5nm (Zollinger, 1987).
