Specifically comparing the effect of solvent on the dipole moment at the nh1 and nh1nh1 ′ structures, it can be seen that across all levels of theory presented, the THF complexes consistently show a higher dipole moment than water for the analogous positions. This is somewhat counterintuitive, considering that experimentally the dipole moments of THF and water in the gas phase are 1.63 and 1.85 debye, respectively. 38
