    • We point out that the accuracy of the experimental data is far better than the one offered by DFT computations. However, trends and vibrational frequency differences among different forms of the same molecule are reliably predicted by these computations

    • A rotation of 180°, which could be considered a better choice, brings two hydrogens at short separation, thus giving a distorted estimate of the hydrogen bond energy
