W4$\hat{I}›$: leveraging $\hat{I}›$ coupled cluster for accurate computational thermochemistry approaches

Emmanouil Semidalas, Amir Karton, Jan M. L. Martin

High-accuracy composite wavefunction methods like Weizmann-4 (W4) theory, high-accuracy extrapolated \textit{ab initio} thermochemistry (HEAT), and Feller-Peterson-Dixon (FPD) enab…
