Abstract
The static structure factors of periodic systems have been deduced fro m ab initio Hartree-Fock calculations. Taking into account atomic ther mal motions, dynamic structure factors at 298 K were then calculated b y assuming that atomic displacements are independent and atomic orbita ls follow nuclear movements. Th ree triperiodic systems have been stud ied: silicon, magnesium oxide and beryllium oxide.
