Local motions of organic pollutants in soil components, as studied by {sup 2}H NMR
- Colorado State Univ., Fort Collins, CO (United States). Dept. of Chemistry
{sup 2}H NMR spectra and interpretations are presented on a series of samples, each consisting of a deuterium-labeled organic pollutant (trichloroethylene, acetone, pyridine, benzene, or ethylene glycol) adsorbed on a soil component (montmorillonite clay or humic acid). Spectra were obtained over a wide temperature range and using two values of the quadrupolar echo delay period. Computer simulations of line shapes resulting from various forms of local motion of C-{sup 2}H moieties provide useful guidelines for interpreting the experimental results. In a few cases, detailed line shape simulations are given. This approach is attractive for elucidation of the detailed motional behaviors of organic pollutants adsorbed in soil.
