| Geometries, energies, and first- and second-energy derivatives of all of the stationary points found here were fully optimized by hybrid density functional theory (DFT) using the GAUSSIAN 09 program suite.[12] For the DFT calculations, we used the hybrid gradient-corrected exchange functional of Lee, Yang, and Parr.[13], [14] The 6-31G[15]basis set with polarization (d and p) were selected for all the atoms except Palladium, for which the Stuttgart-Dresden effective core potential[16] was utilized to accurately account for relativistic effects and to substantially reduce the number of electrons in the system. Vibrational frequency calculations done at the B3LYP/6-31G (d, p) level of theory were used to characterize all of the stationary points as either minima (the number of imaginary frequencies (NIMAG=0) or transition states (NIMAG=1)). The relative energies are, thus, corrected for the vibrational zero-point energies (ZPE, not scaled). |
