6 Molecules as a Basis ' for Modeling the Force Field of Silica

چکیده
More than fifty years ago, John C. Slater (1939), Institute Professor at MIT, noted that the bond lengths and angles of the C6 skeletal ring of the cyclohexane molecule are strikingly similar to those observed for the C framework of diamond. Structural analyses have since revealed that the bond lengths and angles of the C skeletons of several other aliphatic molecules (neopentane, adamantine, congressane, anti-tetramantine) are also similar to those observed for diamond. As observed for the skeletal ring of cyclohexane, the skeletal pattern of the C atoms of anyone of these molecules has only to be extended in three-dimensional space to generate the diamond structure. The close correspondence between these structures provides the basis for Slater's (1939) statement that 'A diamond is really a molecule of visible dimensions

The recognition of the biologically and environmentally important ions is of great interest in the field of chemical sensors in recent years. The fluorescent sensors as a powerful optical analytical technique for the detection of low level of various analytes such as anions and metal cations have been progressively developed due to the simplicity, cost effective, and selectivity for monitoring ...
متن کاملModeling of the hydration shell of Adenine
The molecular geometry of complex of adenine with 8 water molecules was calculated with Hartree-Fock (HF). The standard 6-31G(d) basis set has been employed. The existence of C-H…O Hydrogen bonds between the water molecules and the hydrophobic part of nucleobase is stablished. We optimized structures and computed interaction energies of all complexes of adenine with water molecules step by step...
متن کاملModeling of PDMS - Silica Nanocomposites
A hydrogen bonding pathway between polydimethylsiloxane (PDMS) and hydroxyl groups on a silica surface was studied using quantum chemistry calculations of disiloxane and hexamethyldisiloxane molecules with small silica clusters. A newly developed classical force field for PDMS was developed for atomistic molecular dynamics simulation studies of PDMS – silica nanocomposites to determine the effe...
