摘要：
The splitting seen in the NMR line shape obtained from deformed networks has been cited as evidence of short-range orientational interactions between segments belonging to different chains. In this paper, it is shown that a splitting can still occur when only the usual short-range and isotropic excluded-volume interactions are acting. The orientational effects are shown to originate from the anisotropic screening properties of the deformed network chains.
