氯原子被检测到在其基态和自旋轨道激发态的光解离产物的室温OCIO在波长356-363 nm激发。使用可调谐染料激光器在355-370 nm的波长范围内激发OCIO，并且使用第二可调谐染料激光器经由Cl（和Cl*）原子在235 nm附近的（2+ 1）REMPI光谱探测Cl（和Cl*）原子。在362 nm附近Cl的量子产额为0.15±0.10，基态的量子产额是自旋轨道激发态Cl的5倍。
Chlorine atoms are detected in their groundand spin-orbit excited states as photodissociation products of room-temperature OCIO excited at wavelengths 356-363 nm. A tunable dye laser is used to excite OCIO in the wavelength range 355-370 nm, and a second tunable dye laser is used to probe for Cl (and Cl*) atoms via their (2+ 1) REMPI spectrum near 235 nm. The quantum yield for Cl formation near 362 nm is 0.15±0.10, with about 5 times more ground-state than spin-orbit excited Cl produced.
