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.

The relationship between photons of light at various energies and wavelengths is Given by E=hv , c=v(wavelength) Therefore, when a photon of energy at wavelength of 275 nm is compared with photons of energy at wavelength of 390 nm and higher we have a decrease in the energy and its dissociation energy that would attack polymeric or chemical bonds of various structures. Therefore, the higher the wavelength the lower the frequency or higher wavelengths have less energy than lower wavelengths 275nm is far greater energy than 390nm or higher. Given we have established light is composed of photons and high energy gamma radiation are also photons but of higher energy does the math for photochemistry given above apply to higher sources of photon energy from gamma and other sources of radiation?
