# Optical absorption spectrum of Tetraphenylporphyrin, [TPP] in toluene # # 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 R. W. Wagner in 1994 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 18900 cm-1/M at 515.0 nm. These values were # then interpolated to report extinction coefficients at regular 1nm intervals # # The reported molar extinction coefficient is from # Barnett, G. H., M. F. Hudson and K. M. Smith (1975) Concerning meso-tetraphenylporphyrin purification. J. Chem. Soc. Perkin Trans. I 1401-1403. # ##Wavelength (nm) Molar Extinction (cm-1/M) 349.75 19119 350 19862 350.25 19203 350.5 17719 350.75 19305 351 20629 351.25 20281 351.5 18398 351.75 20852 352 18150 352.25 18560 352.5
