## Quantum Mechanical Calculations for Reaction Path of O-R Bond Breakage in Some of Cefpodoxime Prodrugs: A Scientific Explanation

Unrestricted Hartree Fock (UHF) quantum mechanical calculations of proton transfer and reaction path of (O-R) bond rupture energies in nine cefpodoxime prodrug derivatives of different substituted organic groups, at their optimized geometries, are presented in this work. Using the Gaussian-09
