Photoelectron spectroscopy (PES) can be used to determine:
A.The molecular geometry of a compound
B.The relative energies of electrons in an atom
C.The bond angles in a molecule
D.The melting point of a substance
Explanation
Core Concept
PES measures the kinetic energy of electrons ejected from atoms, which reveals the relative energies of different electron shells and subshells.
Correct Answer
BThe relative energies of electrons in an atom
