Textbook Question
Chapter 6, Problem 39P
The photoelectron spectrum of HBr has two main groups of peaks. The first has ionization energy 11.88 eV. The next peak has ionization energy 15.2 eV, and it is followed by a long progression of peaks with higher ionization energies. Identify the molecular orbitals corresponding to these two groups of peaks.

Correlate the photoelectron spectra of N2 and O2 with their respective molecular orbital diagrams.
Consider the molecular orbital diagram below for carbon dioxide. Refer to the molecular orbitals using the letters on the far right of the diagram
(a) Identify the HOMO to LUMO transition by reporting the initial and final orbitals for each transition. Then calculate the wavelength [in nanometers] and frequency [in Hz] for the photon involved in
the transition if the energy change is 2.0 eV.
(b) Identify the m\pitT-to-TT\piT* and n-to-TT\piTT* transitions by reporting the initial and final orbitals for each transition. Your textbook states than typical transition energies are 7eV (TT\piTT-to-TT\piTT*) and
4 ev (n-to-TT\pir*). Even though the diagram here does not give numerical values for energies, you can still make use of this typical behavior to give you confidence in your answers.
