WebAs can be seen in Table 1, this represents a significant improvement over B2PLYP not just for barrier heights but also for basic thermochemistry and large-molecule reactions. It still outperforms the best rung 4 functional to date, ωB97M-V. Intriguingly, B2GP-PLYP is fairly insensitive to the type of dispersion correction it is paired with.
