08513 IUPAC Gold Book - optical emission spectroscopy 10.1351/goldbook.08513 08513 current initialism: OES 1 Measurement principle of atomic emission spectroscopy in which the emitted electromagnetic radiation is in the range of frequencies from the infrared, through visible, to the ultra-violet region. OES is used as the detector in inductively-coupled plasma optical emission spectroscopy, and glow-discharge optical emission spectroscopy. atomic emission spectroscopy https://goldbook.iupac.org//terms/view/08452 electromagnetic radiation https://goldbook.iupac.org//terms/view/08242 glow-discharge optical emission spectroscopy https://goldbook.iupac.org//terms/view/08483 inductively-coupled plasma optical emission spectroscopy https://goldbook.iupac.org//terms/view/08491 PAC, 2021, 93, 647.
