摘要：

NMR proton, deuteron and oxygen-17 relaxation rates were measured in different isotopic species of liquid butanol, pentanol and hexanol and in their mixtures with carbon tetrachloride at 298 K. From the oxygen-17 induced proton relaxation rate the correlation time, tau(c), of the O-H intramolecular vector was obtained. This value is compared with data from dielectric relaxation measurements, tau(D) and tau(l). The ratio tau(l)/tau(c) agrees well with the well-known relation, tau(l)/tau(c) = 3. Using the correlation time, tau(c), we obtained the deuteron and oxygen-17 quadrupole coupling constants, chi(D) and chi(O) respectively.
