Five different conformer orientations were designed as the starting structures for the conformational analysis of the 1Gal compound. Once the conformers were generated, they were optimised by DFT methodology using the Gaussian16 program. Geometry optimisations and vibrational frequency calculation were carried out at the B3LYP-D3/6-31+g(d) computational level. These calculations were performed in water as the solvent (SMD method) and at a temperature of 298.15K. The vibrational frequencies were used to ensure that the structures were fully optimised and represented a minimum on the potential energy surface.
