Dalitz plots for the comparison of 990 state-to-state transition rate coefficients for para-H₂O + para-H₂ collisions at four different temperatures: 100, 500, 1000, and 1500 K. Each triangular plot represents a comparison between three computational methods: MQCT from this work (AT), full quantum (CC) calculations (Daniel et al. 2011), and full quantum (CS) calculations (Zóltowski et al. 2021) using MOLSCAT. Different red dots within each triangle represent different transitions.
