POLARIZED FT-IR SPECTRA OF ADAMANTANOL DERIVATIVES .3. ADAMANTAN-1-OL AND ITS DEUTERATED ANALOG

The polarized FT-IR spectra of adamantan-1-ol (A1) and deuterated adamantan-1-ol (A1-d) single crystals and their powder spectra have been investigated. The hydrogen bond vibrations are identified at about 3320 and 2460 cm-1 (stretching), 1420 and 1000 cm-1 (in-plane deformation) and 720, 655 and 522, 499 cm-1 (out-of-plane deformation) for the A1 and the A1-d single crystals, respectively. The results are discussed in relation to the selection rules and the oriented gas model approximation. Other internal vibrations in the 4000-400 cm-1 range are tentatively assigned.
