(J|I) to sample the second particle is displayed in Figure . The left, non-logarithmic plot (Figure ) is non-uniform; however, the range of PCHB values is much smaller than for the stack of benzene (Figure ), indicating a more homogeneous distribution. The logarithmic plot (Figure ) reveals that the probabilities range mostly over "just one" order of magnitude, unlike the four orders of magnitude in Figure . There is no obvious exponential decay for the probability of the second particle, due to the compact nature of the system. Overall, the N 2 dimer and similar systems might still benefit from uniform sampling of the second particle p uni 2 (J|I)| J∈|D i . This suggestion is investigated in greater detail and confirmed in Section 5.
