    • a values in solution are difficult to calculate (our attempts using isodesmic reactions indicated a strong dependence of the results on proton donor) such that one cannot reliably estimate the likeliness of protonation from theory alone.

    • note
    • The harmonic frequencies calculated with the BP functional are generally known to compare favorably with experimentally measured fundamental frequencies. This is based on a partial cancellation of errors since the experimental frequencies would have to be corrected for anharmonicities to be strictly comparable to the theoretical numbers.29 However, the anharmonicity corrections are unknown for molecules of the size studied in this work. We therefore directly compare the calculated frequencies with the experimental vibrational frequencies as observed by IR spectroscopy. The experimentally observed shifts within the series of FeNO complexes and in the isotopic labeling experiments are sufficiently large to be unambiguously correlated with the theoretical numbers.
