Chem 120A Problem Set 8 Out Monday 04/30/07; revised Wed. 05/02/07; Due Monday 05/07/07 1. a) Determine the ground state electron configurations of NO + and NO. Compare the bond orders of these two species. b) Determine the bond order for the cyanide ion. c) Consider the heteronuclear diatomic molecule CO. The ionization energies of an electron from the valence atomic orbitals on the carbon atom and the oxygen atom are listed below. Atom Valence orbital Ionization energy/ MJ · mol - 1 O 2 s 3.116 2 p 1.524 C 2 s 1.872 2 p 1.023 Use these data to construct a molecular orbital diagram for CO. What are the symmetry designations of the molecular orbitals of CO? What is the electron configuration of the ground state of CO? What is the bond order of CO? Is it paramagnetic or diamagnetic? 2. The following lines were observed in the microwave absorption spectrum of H 127 I and D 127 I between 60 cm - 1 and 90 cm - 1 . ˜ ν
