science-softCon UV/Vis+ Spectra Data Base (UV/Vis+ Photochemistry Database)

Spectral information (gas, liquid and solid phase from EUV-VUV-UV-Vis-NIR) and related data (e.g.  information concerning publications on quantum yield studies or photolysis studies) from published papers. This database is a work in permanent progress. Additional spectra and datasheets will be added continuously.

Database access. Spectra Service (via IP-number), Spectra Service (via password), list of universities/governmental organizations which have campus-wide full access via IP-number.

One-time registration for University libraries and libraries of governmental research centers allows unlimited full access to the "Spectra Service"

To minimize the bureaucratically expenditure a one-time registration for university libraries and governmental organizations is possible from now on. However, we do charge a one time registration fee of 950 EURO for such institutions to help maintain this non-profit service to the scientific community. So, a one-off expense, which includes the latest issue of the “UV/Vis+ Spectra Data Base” CD-ROM series, will provide your institution permanent access to this fast growing database (spectral data, datasheets, additional photochemistry data and information) via IP-number. Please note that the database is more than 19 years on-line and in permanent progress, additional spectra/datasheets will be added continuously. For more information please contact our helpdesk.
