Abstract
The nuclear magnetic relaxation characteristics of ({sup 13}C)methanol adsorbed to sol-gel silica were studied over a wide range of temperatures. The four-line spectra displayed different T{sub 2} values for each line. Inner and outer lines of the quartet displayed different T{sub 1} values. This behavior indicates that temporal correlations between different carbon-proton dipolar interactions are significant. Cross correlations between carbon-proton dipolar couplings and the carbon chemical shift anisotropy are discernible. Adsorbed methanol presents an interesting situation where both even and odd ranks of multispin order are spawned from athermal magnetizations via orientationally dependent spin interactions. These interactions are modulated by highly anisotropic molecular motions.
