N 2 van der Waals complex is generated using the explicitly correlated coupled cluster with
single, double, and perturbative triple excitation (CCSD (T)-F12) method in conjunction with
the augmented correlation consistent triple zeta (aug-cc-pVTZ) basis set. This 4D-PES is
mapped along the intermonomer coordinates. An analytic fit of this 4D-PES is performed.
Our extensive computations confirm that the most stable form corresponds to a T-shape …
