# Optical absorption spectrum of Pyropheophorbide a in dichloromethane # # Data from PhotochemCAD 2.1a has been munged on 2 June 2017 by Scott Prahl to make # the information available to non-Windows users. Although I have tried to be as careful # as possible, I may have introduced some error; the cautious user is advised to compare # these results with the original sources at www.photochemcad.com: # # H.

Taniguchi and J. S. Lindsey "PhotochemCAD 2. A refined program with accompanying # spectral databases for photochemical calculations", Photochem. Photobiol., 81, 212-213, 2005. # # The spectral absorption measurements were made by M. Taniguchi on 10-03-2004 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 45000 cm-1/M at 669.0 nm. These values were # then interpolated to report extinction coefficients at regular 1nm intervals # # The reported molar extinction coefficient is from # Zheng, G., H. Li, M. Zhang, S. Lund-Katz, B.
