The molecular dynamics (MD) technique was used to investigate the nano droplet
composed of twenty mesogene molecules 4-cyano-4-n-pentylbiphenyl (5CB). The 5CB molecules
were treated as rigid bodies, the intermolecular interaction was taken to be the full site-site pairwise
additive Lennard-Jones (LJ) potential plus a Coulomb interaction. The radial distribution functions
in the temperature range from 150 to 400 K, were calculated as well as the linear and angular
velocity autocorrelation functions. In addition the total dipole moment autocorrelation function and
dielectric loss of (5CB)22 mesogene cluster were calculated and the liquid crystal ordering in the
nanoscale system was studied up to its vaporization temperature.
