Abstract:
Theoretical studies on various geometrical structures of Hypophosphorous acid were carried out using DFT theoretical methods, at the B3LYP/6—311++G** level. Intramolecular proton transfer isomerization has also been studied using the intrinsic reaction coordinate. The results show that thione isomer is stable with respect to thiol isomer from energetically, lower -26.2 kJ/mol corrected with zero point vibrational energy. The proton transfer reaction was characterized by the structure with a tetra-atomic ring.
KeyWords:
