Raman and infrared spectra of cellobiose in the solid state: What can be learned from single-molecule calculations? Academic Article uri icon

abstract

  • Fourier-transform infrared and Raman scattering spectra of solid cellobiose are measured. The monitored spectra are compared to vibrational spectra of isolated cellobiose, computed by the vibrational self-consistent field (VSCF) method and from classical molecular dynamics (MD) simulations. Partial agreement is found between the measured and calculated features, allowing interpretation of parts of the spectra in terms of single-molecule calculations. Deviations between the measured spectra and the calculated ones could be due to environment effects on the molecule, not included in the model, or due to errors in the vibrational methods used. Future investigations of this issue seem desirable.
