In addition, current commonly used molecular force fields do not take electronic polarizability into account, which could be an important property in determining protonation energies.
2.
This results because the parylene repeat units possess a phenyl ring and due to the high electronic polarizability of the phenyl ring adjacent repeat units order themselves in the XY-plane.
3.
The large numerical value of ? r is not surprising in the second case, as the iodine atom is easily polarizable; nevertheless, this does not imply that it is polar, too ( electronic polarizability prevails over the orientational one in this case ).
4.
The van der Waals term is usually computed with a Lennard-Jones potential and the electrostatic term with Coulomb's law, although both can be buffered or scaled by a constant factor to account for electronic polarizability and produce better agreement with experimental observations.
5.
Solvent contained in the film usually does contribute to the acoustic thickness ( because it takes part in the movement ), whereas it does not contribute to the optic thickness ( because the electronic polarizability of a solvent molecule does not change when it is located inside a film ).
