The structure, interaction energy and proton-transfer features of the ( Hs02) + complex are determined by using a nonlocal density functional theory method developed recently by Salahub and co-workers, The results are compared to those of a highorder Moller-PIesset electron-correlation calculation.

โฆ Synopsis
Density functional calculations are carried out for the HsB-NH3 system and compared with experimental and ab initio theoretical data. Calculations that use non-local exchange-correlation potentials are capable of providing excellent geometries, dative bond energies and dipole moments, as well as adequate estimates of vibrational frequencies and barriers to internal rotations. The local density approximation can provide reasonable structure information, but significantly overestimates the dative bond energy,

## Abstract **Summary:** Details of the dynamic density functional theory for sheared polymer systems are presented. The method is illustrated on polymer blends with and without compatibilizers. Shearing slows down coarsening of structures at later stages of phase separation, trapping the system in
