Suppose a diatomic molecule absorbs 200nm light, which excites it into its first excited state. The molecule then dissociates, and 90% of the light energy is converted to kinetic energy. What is the kinetic energy of each atom? What is the total kinetic energy of a mole of these dissociations? Discuss.
Electronic Transitions and Spectroscopy
The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.
Photoelectron Spectroscopy
Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
