Vibrational spectra of chitin have been analysed using the DFT monomer approach, and complete assignments of experimental FTIR signals are being reported in the present work. DFT calculations with the 6-311G basis set produces results for vibrational modes that reasonably agree with the experimental ...

The efficiency of the analytical methods based on vibrational spectroscopy has been widely verified in a high number of publications. In addition, it has been recognized that the pretreatment of the original signals is absolutely necessary to obtain enough quality in the subsequent classification and/...
If you have a sample that needs a different configuration setup (due to very weak or strong signals), please make changes according to the explanation for each tab below. You can save your own setup file under a new name. Please note that the actual screens may look a little bit ...
