Abstract We have applied DMC to evaluate relative stability of Increasing levels of zeolite and Yucca schidigera in diets for adult cats the possible electronic configurations of an isolated FePc under D 4h symmetry, considering some fixed nodes generated from different methods.They predict A 2g ground state consistently, supporting preceding DFT studies, with confidence overcoming the ambiguity about exchange-correlation (XC) functionals.By comparing DMC with several XC, we clarified the importance of the short-range exchange to describe the relative stability.

We examined why the predicted A 2g is excluded from possible ground states in the recent ligand field based model.Simplified assumptions made in the superposition model are identified to give unreasonably less energy gain for A 2g when compared with the reality.The state is found to have possible reasons for the stabilization, reducing the occupations from an unstable anti-bonding orbital, avoiding double Carcass detection and consumption by facultative scavengers in forest ecosystem highlights the value of their ecosystem services occupation of a spatially localized orbital, and gaining exchange energy by putting a triplet spin pair in degenerate orbitals.
