Fig. 4.
Molecular decomposition pathway of phosphino formic acid (H2PCOOH) (a) and of the isovalent formic acid (H2NCOOH) (b). Energies were obtained at the CCSD(T)/CBS level with B3LYP/cc-pVTZ zero-point vibrational energy corrections. Partial charges (e) of the species related to the decomposition of phosphino formic acid (H2PCOOH) and carbamic acid (H2NCOOH) are also indicated.
