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.

Spectroscopy, or the study of how light interacts with matter, is an extremely powerful tool scientists use to identify unknown
substances. One branch of spectroscopy is the measurement of the interactions between gases and visible light.
Sending a very high voltage through a gas adds energy to the system causing some of the electrons to enter a more unstable, or
excited, state. To return to the stable state, the electron emits scme of that energy in the form of light.
Using the fact that electrons can only exist in certain energy "shelves," we can predict what wavelengths of light, or colors, are emitted
when we add energy to the system. The following equation shows the energy levels for a hydrogen atom with only one electron (when
dealing with multiple electrons and protons the math becomes far more complex and is outside the scope of this activity).
