The correlations between interaction and relative conformer energies of the different attraction . In those reports, it has been shown that the nature of the interaction between the C 1 -H 1 hydrogen atom of [EMI] + cation and a range of anions is considerably different from that of conventional hydrogen bonds and this interaction does not show any dependence on orientation for these authors have found that small angles (lacking directionality) in energetically more stable conformers than in the ones with linear arrangement .
