Molecular vibrational spectra in 3, 3-dimethyl-1-butanol, (CH3)3 CCH2CH2OH, and 3, 3-dimethyl-2-butanol, (CH3)3CCHOHCH3, were measured by the inelastic incoherent neutron scattering and mid infrared spectroscopy and for 3, 3-dimethyl-2-butanol additionally by the far infrared absorption method. Experimental results were discussed and compared with the results of the quantum chemical calculations performed by the density functional theory (DFT/B3LYP/6-311G**) and semi-empirical PM3 calculation methods assuming the isolated molecule approximation.
