The characteristic orange light produced by sodium in a flame is due to the intense emission called the "D" streak from sodium. This "streak" is actually a doublet, whose wavelengths (measured in vacuum) are 589.15788 and 589.75537 nm. The refractive index of air in the vicinity of 589 nm is 1.0002926. Calculate the frequency, wavelength, and wave number of each component of the "D" line, measured in air.

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.
