Analytical infrared intensities for periodic systems with local basis   sets
  We report a method for the efficient evaluation of analytic infrared (IR) intensities within generalized Kohn-Sham density functional theory using Gaussian orbitals and periodic boundary conditions. A discretized form of the Berry phase is used to evaluate a periodic dipole moment and its derivatives with respect to in-phase nuclear coordinate displacements. Benchmark calculations are presented for one-dimensional chains of water molecules and poly(paraphenylenevinylene).
