Lattice statics and dynamics calculations for cu-nitrogen have bees done using the fi-exp aeoin-atom titenction to derive intennoldcular forces. The three pammeters of this interaction ue reduced to one by cunskeining them so that the uo.it cell and sublimation energy are calculated to agree with ex
The conlniution to\_btbce dynamics of molecular crystals of polarization interaction due Lo dipoles induced by the molecular multipolar field has been evaluated by calculation of the lattice frequencies of crystalline ammonia\_ It has been found that this contribution is small but not negligible.
A quasiharmonic central-force rigid-atom model has been used to study the dispersion of phonon waves in molecular (rare-gas) solids. The model derives the interatomic forces by Buckingham-Corner potential and takes account of all neighbor interactions. Zero-point anharmonic effects have been taken i
The crystal nucleation of nitrogen is studied by molecular dynamics. Using the umbrella sampling technique, we are able to determine the free energy barrier of nucleation and the structure of the critical nucleus formed under typical experimental supercoolings. In agreement with OstwaldΓs Γstep rule
