A staged quench sequence was used to generate nucleating trajectories. The five configurations were first quenched to 300 K, and equilibrated for 100 million time steps (∼2 µs) at 300 K and 1 atm using NPT simulations. The n-C 720 H 1442 melt is metastable at these conditions on the timescales considered in this study. The final configurations from the 300 K simulations were then quenched to 270 K, and evolved for another 20 million time steps (∼204 ns) while pressure was maintained at 1 atm. The final configuration from each of the five NPT simulations at 270 K was used to start one NVT and one NVE crystal nucleation simulation. The NVT simulations had their temperatures maintained at 270 K. Minimal crystallization occurred during the preparatory NPT simulations at 270 K as evidenced by the trace amounts of crystallinity at the start of the simulations (e.g., see Fig. ). The NVE and NVT nucleation simulations at 270 K were 200 million time steps long (∼2 µs). The NPT nucleation simulations were performed by quenching the final configurations from the 300 K simulations to 270 K, and evolving the corresponding systems for 200 million time steps (∼2 µs). To be consistent with the NVE and NVT nucleation simulations, data from the first 20 million time steps of the NPT nucleation simulations were discarded; minimal crystallization had occurred during that time.
