The torsional freedom of the carbon backbone and hydroxyl groups induces numerous plausible conformers. Rotational spectroscopy supported by quantum chemical methods evidences that the “folding of methylene unit” is favoured.

In Silico Methods

The storage of hydrogen is the key technology for a sustainable future. We developed an in silico procedure, which is based on the combination of experimental and quantum-chemical methods. This method was used to evaluate energetic parameters for hydrogenation/dehydrogenation reactions of various pyrazine derivatives as a seminal liquid organic hydrogen carriers (LOHC), that are involved in the hydrogen storage technologies. With this in silico tool, the tempo of the reliable search for suitable LOHC candidates will accelerate dramatically, leading to the design and development of efficient materials for various niche applications.

Reactions between water clusters containing the superoxide anion, O2˙−(H2O)n (n = 0–4), and formic acid, HCO2H, were studied experimentally in vacuo and modelled using quantum chemical methods.
