Energy level — A quantum mechanical system or particle that is bound that is, confined spatially can only take on certain discrete values of energy. This contrasts with classical particles, which can have any energy. These discrete values are called energy… … Wikipedia
Rotational spectroscopy — Part of the rotational vibrational spectrum of carbon monoxide (CO) gas (from FTIR), showing the presence of P and R branches. Frequency is on the x axis, and absorbance on the y axis. Rotational spectroscopy or microwave spectroscopy studies the … Wikipedia
Fine structure — Interference fringes, showing fine structure (splitting) of a cooled deuterium source, viewed through a Fabry Pérot étalon. In atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to first order… … Wikipedia
