摘要
The polarized FTIR-spectra of the 2-phenyladamantan-2-ol (PA2) single crystal and powder spectra of the PA2 and deuterated PA2-d samples have been investigated. The results indicate that the OH groups are involved in weak OH⋯O hydrogen bonds. The hydrogen bond vibrations are identified at 3375 [ν(OH)], 1395 [δ(OH)] and about 600 cm-1 [γ(OH)] and discussed in relation to the selection rules and to the oriented gas model approximation. Davydov splitting of the out-of-plane deformation mode γ(OH) is observed. The other internal vibrations in the range 4000-400 cm-1 are tentatively assigned. © 1990.
