Biphenyl intermolecular forces
WebLondon Dispersion Forces We could discount intermolecular interactions between gas-phase molecules because these molecules are mostly far apart and moving rapidly relative to each other. In the liquid phases, all molecules interact with one another. The stronger the interaction between a molecule and a pure liquid, the greater will be the ... WebDec 21, 2005 · The combination of optical-Kerr-effect (OKE) spectroscopy and molecular dynamics simulations has provided us with a newfound ability to delve into the librational dynamics of liquids, revealing, in the process, some surprising commonalities among aromatic liquids. Benzene and biphenyl, for example, have remarkably similar OKE …
