Performance of a kinetic energy density-dependent functional (VSXC) for predicting vibrational frequencies

We present a study of the performance of the VSXC functional for predicting vibrational frequencies and equilibrium geometries and compare the results with experiment and the B3LYP functional. The standard 6-31G∗ and 6-311++G(3df,3pd) basis sets were used for both functionals. Scaling factors for obtaining fundamental vibrational frequencies have been derived using a least-squares approach. VSXC results compare favorably with experiment and those of B3LYP for both basis sets.
