Correlation ZPE

Hi, I started to use Psi4 for generating Arkane input files but I got an error message from Arkane below

arkane.exceptions.LogError: Unable to find zero-point energy in Psi4 output file

The reason why I got this message is that correlation ZPE doesn’t exist in frequency file and I searched for how I can calculate correlation ZPE with Psi4 but I couldn’t find it. Is it possible to calculate correlation ZPE with Psi4? I added my simple code below

  1. Please follow our best practices for posting topics. I specifically refer you to backticks.
  2. What is a “correlation ZPE” for Hartree–Fock? I know what a zero-point energy is. I can imagine with a correlation ZPE would be for a post-Hartree–Fock method (though I can’t imagine why a chemical kinetics program like Arkane would need that). But I have no idea what a “correlation ZPE” for Hartree–Fock would be.
