Chapter 9, Problem 9C.4P

Interpretation Introduction

Interpretation:

The molecular orbital energy level diagram for the species, showing the ionization energies of the three identifiable orbitals has to be sketched.

Concept introduction:

The ejection of electrons from the surface of an object takes place, when it absorbs certain range of radiation.  Thus, there is a minimum energy require to eject an electron from the surface.  This energy is called as work function.  The energy of the incident photon is equal to the sum of the kinetic energy of ejected electron and the ionization energy of the sample.
