## Abstract The effect of the location of the halogen atom on the distribution of activation energies associated with the subglass relaxation of poly(__o__βchlorophenyl acrylate) (POCPA) and poly(__m__βchlorophenyl acrylate) (PMCPA) is studied. Poly(__pβ__chlorophenyl acrylate) (PPCPA) was also inv
The relaxation of multiple quantum transitions in a heteronuclear three-spin system is described in terms of Redfield theory including intramolecular dipolar and chemical shift anisotropy (CSA) mechanisms. CSA-dipolar cross-correlations, interference terms between CSA terms at different nuclear site
Fluorine is often used in drug-design efforts to enhance the pharmacokinetic properties of biologically active compounds. Additionally fluorine nuclei ( 19 F) have properties that are well suited to current pharmaceutical NMR screening programs. Together, these considerations have motivated our inte
The cross-correlation spectral density of chemical shift anisotropy and dipolar interactions in isotropic solution of methyl formate is measured using a novel NMR technique designed to monitor the appearance of longitudinal two-spin order 2I,S, during mversion recovery. The result is tentatively int
