โœฆ Synopsis

The 3p 5 , 2 P1/2 ~ 2P3/2, fine structure transition in the chlorine atom has been detected using a tunable infrared diode laser operating near 11.3 ~m. Relative spacings of the 35 C1 and 37C1 hyperfine components are in excellent agreement with measurements of atomic beam radiofrequency spectroscopy of CI(2pj) and the isotope shift determined by laser magnetic resonance.

Time-resolved diode laser absorption spectroscopy is used to probe Cl atoms produced from the photolysis of a number of molecular precursors at excimer laser wavelengths 193,248 and 308 nm. The diode laser was tuned to the Cl atom tine structure transition, 2PJ,2+2P,,2. For 248 and 193 nm photolysis
