The orientational ordergenerated in uniaxially strainedelastomers is probed with deuterium NMR. Perdeuterated swelling agents exhibit quadrupolar splittings which have an explicit dependence on the extension ratio, degree of swelling, and temperature. A phenomenological description based on a lattice model of the deformed, swollen network which includes short-range nematic-like interactions successfully accounts for the observations. The implications that these findings have for the opticoelastic behavior of swollen networks are emphasized.
