Interacting nanoparticle systems field dynamics

Aniotropb fluctuatbn Iheshapes. Rancourt and Daniels (1984) showed that the i+ and T values that arise from typical interaction fields, with typical values of fo, give dynamic lineshapes of sextets having broad and asymmetric absorption lines similar to the observed ones in many nanoparticle systems. This suggests that the often extracted HFDs are artefacts of an incorrect spectral analysis. One difficulty that inhibited the... 

Force-field molecular dynamics simulations offer the ability to model molecules at the particle level. Often, information from quantum simulations is used to develop the empirical equations (force-field) that are used to govern the interactions between particles. Because force-field molecular dynamics simulations use less detail than the quantum simulations, they are able to model systems that are significantly larger in size ( 10 particles) for a longer period of time (<10 s). Therefore, measuring the structural, mechanical, and/or transport properties of medium to large sized systems (i.e., proteins, functionalized nanoparticles,...) is possible.
