FTIR spectra of monohydric alcohols 1-nonanol (C9H19OH) and 1-decanol (C10H21OH) were registered in the spectral region from 500 cm-1 to 4000 cm-1 at temperatures from -50 to + 25 {\deg}C for 1-nonanol and +100 {\deg}C for 1-decanol. Temperature-induced spectra changes were compared for these two alcohols. The authors link the observed changes with the transformations of cluster structure occurring during phase transitions.
