      More Details Abstract Fulltext PDF

      Experimental potential energy curve for the X2Π state of AsS has been constructed using the method of Rydberg-Klein-Rees. The precise dissociation energy for the ground state has been estimated as 4.150±0.13 eV by the curve fitting procedure. The first ionization potential of the AsS molecule is found to be 8.66 eV.

      More Details Abstract Fulltext PDF

      The parameterS0 which is characteristic of molten alkali halides and liquids has also been shown to be characteristic of a wide variety of polymers. Calculated data using the volume expansivity of the polymer establish the temperature invariance and constancy of theS0-parameter which retains, on an average, a constant value of 1.11 for polymers. Further understanding of the significance of fractional free volume andS0-parameter in describing various thermoacoustic properties and the anharmonic behaviour in polymers, has been developed.
