Near-infrared spectra of 1-alcohols from methanol to 1-decanol in the pure liquid phase were recorded from 5200 to 9000£¿cm£¿1. The similarities and differences between the spectra were analyzed by the classical and chemometric methods (principal component analysis). The obtained results reveal that the near-infrared spectra of methanol, ethanol, and 1-propanol are appreciably different from the spectra of higher 1-alcohols. As shown, the degree of self-association of 1-alcohols decreases with the increase in the chain length %K Near-infrared spectroscopy %K alcohols %K spectra-structure correlations %K chain length effect %U https://journals.sagepub.com/doi/full/10.1177/0960336019836861
