Pressure induced orientational ordering in p-terphenyl

A study uses four different sets of intermolecular and intramolecular potentials to investigate p-terphenyl at 300 K and 1 atm pressure. Results are in excellent agreement with X-ray diffraction results, which also suggests the existence of a similar transition as a function of pressure in polyphenyls such as biphenyl and p-hexaphenyl.
