Table 2 Number of conformers required to achieve 90% of the MS-HO partition function, \(N_{90}\), at 300 K. The table also collects the highest relative electronic, \(E^{\mathrm{max}}\), and free, \(G^{\mathrm{max}}\), energies within the considered conformers. Finally, it also includes the maximum contribution of a single conformer (\(\chi _i^{\mathrm{max}}\)) to the partition function
