The UV-vis and variable-temperature X-band EPR spectral studies (298-77 K) on p-cation of zinc(II) tetraphenylporphyrin (ZnTPP) have revealed for the first time a labile electronic ground state. The electronic structure changes from 2 A 2u to 2 A 1u as the temperature is lowered from 298 to 150 K. A
