Photobiol., 81, 212-213, 2005. # # The spectral absorption measurements were made by R.-C. A. Fuh on 06-23-1995 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 44900 cm-1/M at 459.5 nm. These values were # then interpolated to report extinction coefficients at regular 1nm intervals # # The reported molar extinction coefficient is from # Bourson, J. and B.
