Emissions at 450 nm and 4.27 ~sm have been measured when a vaxiety of mixtures containing H 2, CO. either 02 or NaO, and Ar were heated behind reflected shock waves to temperatures of 2000-2850 K and total concentrations near 5 x 101| molecule/era 3. These emissions were used to obtain absolute con
Time-resolved atomic absorption spectroscopy in the vacuum ultraviolet has been employed to monitor electronically excited oxygen atoms, 0(2\*D2), following their generation by the flash photolysis of ozone in the Hartley band region. We report the first values for the absolute second-order rate con
