Raman Spectra of Carbohydrates

by Søren Balling Engelsen

SPECARB is an experimental database containing Raman spectra of carbohydrates. It is intended to contain solid state Raman spectra of carbohydrates from the monomers and their derivatives to complex polysaccharides. Unless otherwise stated, the spectra are sampled on a Perkin Elmer System 2000 interferometer using a Nd:YAG laser. To obtain comparable spectra they will be recorded using the following parameters:

Excitation: 1064 nm
Laser power: 400 mW
Raman shift: 3600-0 cm-1
Accumulations: 256
Resolution: 4 cm-1

The SPECARB spectra will be available for download in GIF and Perkin Elmer ASCII formats, respectively.

If you have any comments or suggestions for improvements to the SPECARB database, please contact the SPECARB administrator (S.B. Engelsen). Furthermore, we would like to encourage other scientists with high quality Raman spectra of carbohydrates or carbohydrate-related substances to contribute to the SPECARB database. For this purpose, it is sufficient to mail a PE-ASCII file to the administrator along with relevant substance information.
