Question: 1. What is the wavelength of one ultraviolet (uv) photon if the frequency is 1.50 x 1015 g-1? II. What is the energy of one uv photon of this frequency? III. What is the energy of one mole of uv photons of the same wavelength? Hint: What is the relationship between frequency of light and its wavelength? What is the relationship between the energy of a photon and its wavelength? Use equations E01-6-1 and E01-6-2 to find the relationship. See this sample problem if you need help.

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.
