An electron in the 7 orbital of ethylene (C,H,) is excitedby a photon to the * orbital. Do you expect the equilib-rium bond length in the excited ethene molecule to begreater or less than that in ground-state ethene? Will thevibrational frequency in the excited state be higher orlower than in the ground state? Explain your reasoning.

When an electron is excited from bonding to antibonding orbitals by absorption of photon, the bond…

Answered: An electron in the 7 orbital of…
