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
Population inversion — In physics, specifically statistical mechanics, a population inversion occurs when a system (such as a group of atoms or molecules) exists in state with more members in an excited state than in lower energy states. The concept is of fundamental… … Wikipedia
High resolution electron energy loss spectroscopy — (HREELS) is a kind of surface vibrational spectroscopy. A fraction of the incident electrons lose energy by exciting atomic and molecular vibrations at the surface, leading to energy loss peaks that can be observed.Since vibrational energies in… … Wikipedia
