FT-NIR SPECTROSCOPY OF SOME LONG-CHAIN FATTY-ACIDS AND ALCOHOLS

Fourier-transform (FT) near-infrared (NIR) spectroscopy has proved to be a powerful technique in investigating structure and thermodynamic p roperties of long-chain fatty acids and alcohols. In order to extract useful information from the NIR spectra, bands due to the second as we ll as first overtones of OH-stretching modes of the monomeric forms we re employed. It has been also found that two-dimensional (2D) NIR corr elation spectroscopy can accentuate useful information often obscured in the complicated NIR spectral data set.
