Abstract

Infrared spectra of isotopically diluted and pure ethanol crystals at temperatures down to 18 K are reported. A structure in the stretching (ν1) and out-of-plane bending (ν4) bands of isotopically diluted OH-and OD-groups has been found. The results confirm the structural data about the existence of two independent sets of hydrogen bonds in cold ethanol crystals, yield their quantitative relationship (1:2) and indicate the existence of previously unobserved structural rearrangement in the temperature range 60-80 K.
