# Optical absorption spectrum of Nile Blue in ethanol # # 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. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design # and research tool in photochemistry," Photochem. Photobiol., 68, 141-142, 1998. # J. M. Dixon, M. 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 R.-C. A. Fuh on 06-24-1997 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 76800 cm-1/M at 627.5 nm. These values were # then interpolated to report extinction coefficients at regular 1nm intervals # # The reported molar extinction coefficient is from # Birge, R. R. (1987) “Kodak Laser Dyes,” Kodak publication JJ-169. # ##Wavelength (nm) Molar Extinction (cm-1/M) 219 19060 220 18856 221 18544 222 18226 223 18004 224 17871 225 17842 226 17938 227 18118 228 18344
