Effective model-free parameters. (Left) Effective order parameters for different jump angles Δθ ≡cos⁻¹[n ₁ · n ₂]. τ_c ¹ = 5.56 ns, τ_c ² = 2.38 ns. (Center) ${\tau }_c^{\text{eff}}/{\tau }_c^{\text{av}}=\bar{D}/D_{\text{eff}}$ as a function of 6ΔDτ_e ^true for pairs of states with different rotational constants. (Right) Values of τ_c ^eff (solid lines) and τ_e ^eff (dashed lines), plotted against τ_e ^true = (k ₁ + k ₂)⁻¹. In all cases, p _eq(1) = p _eqx(2) = 0.5.
