Structural and dynamical aspects of the incommensurate molecular system Bis(4-chlorophenyl) sulfone

Abstract Bis(4-chlorophenyl)sulfone is a molecular compound whose structure results from the Van der Waals forces and dipolar moment interactions. The region of diffuse scattering in the range 300 K to the transition temperature TI = 150 K and the location of the incommensurate satellites from TI to 0 K, are very weakly temperature dependent demonstrating the existence of some intrinsic structural character. Neutron scattering results combined with light scattering, 35Cl NQR and X-ray analysis reveal peculiar structural and dynamical features in the compound.
