## Abstract The ^1^Hβ and ^13^CβNMR spectra of __N__βacetylβLβalanine methylester and __N__βacetylβLβalanine methylamide were measured to examine the modes of selfβassociation of these molecules in solution. The different dilution shifts between these molecules seem to correspond to the difference

The longitudinal relaxation rate of the first stable alanine radical, SAR1, was studied by employing pulse EPR technique over a wide temperature interval (5-290 K). The complex nonexponential recovery of the longitudinal magnetization in this temperature interval has been described with two characte
Measurements of average free volume hole sizes, Νv f Ν, and the fractional free volumes, f ps , in vulcanized cis-polyisoprene (CPI), high-vinyl polybutadiene (HVBD), and their 50 : 50 blend were made via determination of orthopositronium annihilation lifetimes. The results are compared to correspon
