Table 3. Classification of the Transition Paths in System 2 in Terms of the Residence Time, τ_b, and the Number of Recrossing Events, N_b, at the Free Energy Barrier (i.e. transition state).

Group	Residence time,τ_b (ps)	Number of recrossings, N_b	Path type
A	τ_b ≤ 0.5	2–5	Fast
B	0.5 < τ_b ≤ 2	3–10	Moderate
C	2 < τ_b ≤ 5	5–30	Moderate
D	5 < τ_b ≤ 8	10–40	Slow
E	8 < τ_b ≤ 10	20–65	Slow
