Streszczenie

Generalized two-dimensional(2D)correlation spectroscopy has been applied to the near-infrared (NIR) region for the first time to investigate temperature-dependent spectral variations of cw-9-octadecen-l-ol (oleylalcohol) in the pure liquid state.The 2D correlation spectroscopic analysis has provided spectral information no treadily accessible from conventional one-dimensional spectra. Forexample,the analysis has shown that a bandat 7090cm-1 dueto the first overtone of an OH stretching mode of the monomeric alcohol consists of two bands arising from the rotational isomerism of the free OH group.The existence of a band due to free terminal OH group sof the linear polymeric species has also been suggested from asynchronous 2D NIR  correlation spectrum of the alcohol. An asynchronous 2D NIR spectrum of the alcohol has indicated that the pattern of the temperature dependence for the peak intensity at 7090cm-1 is different from other bands near 6300cm-1 attributed to the polymeric forms of the alcohol.
