The shift to a higher C-N stretching frequency for σ-bonded isonitrile complexes is thought to be due to an increase in the effective positive charge on the carbon atom upon donation of its lone pair. This leads to an increase in the polarity of the C-N bond and hence to an increase in its strength and stretching frequency, see: Wiley: New York

act can be attributed at least in part to the neglect of multiple polarization and diffuse functions in the basis set, leading to an inferior description of the transition state in comparison with the reactant and products. We note that the choice of the basis set was determined by the size of the systems in question, and its enlargement would have made the calculations prohibitively time-consuming.
