Dynamics and structure of tri-n-butyltin fluoride in n-hexane solutions were probed using (tin-119) nuclear magnetic resonance spin relaxation methodologies. Significant relaxation-induced polarization transfer effects were observed and exploited. The experimental observations indicate that the tri-n-butyl fluoride exists in a polymeric form in solution. For a 0.10% (w/w) solution at 25 [degree]C, NMR reveals significant orientational/exchange relaxation on both the microsecond and nanosecond time scales. Solution-state and solid-state parameters are compared and contrasted. 26 refs., 3 figs., 1 tab.
