Section 2.2.2.2 of the manual, “Reading Q-Chem Outputs”, says:
" The qarchive format is HDF5-based, supports more of Q-Chem’s novel feature set than fchk files, and is tightly integrated with IQmol."
How exactly do I use this file in IQmol (V3.1.4, MacOS)? Just plopping it in there as I do with any other file does nothing.
