title: Intrinsic proton relaxation parameters of hydrated polyglycine from two-dimensional time domain NMR
abstract: Proton two-dimensional time domain nmr involving T(1), T(1rho), T(1D), and T(2) measurements was applied to hydrated polyglycine powders. The results were analyzed for magnetization exchange and found to be consistent with a general three-site (glycine-water-glycine) exchange model. The intrinsic glycine and water proton relaxation parameters as well as the three exchange rates were obtained. Estimates of correlation times for water molecule motion at hydration sites are presented. Copyright 1999 John Wiley & Sons, Inc.
