Table 5 Effect of the functional used in the direct AIMD calculations on the time of π-stacking formation (in fs) in (Bz)2+ (no-H2O) and (Bz)2+-H2O (H2O). The CAM-B3LYP/6-311++G(d,p) optimized geometries were used as the initial geometries at time zero. The direct AIMD calculations were carried out using 6-31G(d) basis set.
