The Naturallly Derived Porphyrin Database has been updated to Version 2. The updated database V2 is avilable on the Downloads page.
January 31, 2013
New additional database: Naturally Derived Porphyrin Database
Current Release: Version 2.1 (03/06/2009)
We have revised two spectra in the PhotochemCAD™ database. The spectra pertain to:
(i) The emission spectrum of benzene. A new emission spectrum for benzene has been installed.
(ii) The molar absorption coefficient of chlorophyll b. The molar absorption coefficient for chlorophyll b was previously offset by ~20 nm.
No functions were changed in this release.
Note that when the result of spectra manipulation includes a negative region in the y-axis, the negative region of the spectra cannot be seen automatically. The y-axis of the graph needs to be set manually to an appropriate region to display the negative region of the spectra. This issue should be addressed in a subsequent release.
Development support: 1996-today
The development of PhotochemCAD™ since 1996 has been supported by a grant from the United States Department of Energy, Office of Basic Energy Sciences.
