| Abstract | The considerable diffusivity difference of substituted benzenes and of alcohols in octan-1-ol1 suggests a strong influence of specific solute-solvent interactions (hydrogen bonding). For the quantification of these effects we dried to detect correlations between the diffusion coefficients in octan-1-ol and the near infrared (NIR)-spectra of the solutions. In our study we chose four aliphatic alcohols, benzene, phenol and seven substituted benzenes. By means of different methods of multivariate analysis (PCR, PLS) we tested the possibilities of the classification and prediction of diffusion coefficients using NIR-spectra. From the preliminary results and under the usual assumption that NIR spectra refer to specific solute–solvent nteractions it can be concluded that these interactions also play an important role in the diffusive transport mechanism in liquid octan-1-ol. |
