  Conformational analysis of the experimentally recorded IR absorption spectra
of propanol in a gaseous state and in a low-temperature argon matrix at 20 K
and at 35 K was carried out for different spectral ranges. It showed that the
conformational composition of the samples in gas and in matrix isolation is
different. In gaseous propanol, Gt conformers predominate, while in matrix
isolation the most energetically favorable form is Tg conformer, which prevails
in percentage at both considered temperatures of an Ar matrix.
