When metallic sodium is dissolved in liquid sodium chloride, electrons are released into the liquid. These dissolvedelectrons absorb light with a wavelength near 800 nm.Suppose we treat the positive ions surrounding an electroncrudely as defining a three-dimensional cubic box of edgeL, and we assume that the absorbed light excites the electron from its ground state to the first excited state. Calculate the edge length L in this simple model.

Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.
