## Abstract The sorption of water vapor on two heat shield composites SLAβ561 and SLAβ561V and the SLA components was measured over the pressure range of 10^β3^ to 10 torr and at 25Β°, 30Β°, and 35Β°C. The sorption of water vapor by both the composites and the components varied directly with pressure

Reflected shock waves were used to heat N20/C2H6/CO/Ar and N20/CH4/CO/Ar mixtures to temperatures of 1875-2855 K at total concentrations of 5 Γ 1018 cm -a. Oxygen atom production was monitored via the flame band emission at 450 nm, and CO 2 production was observed at 4.27 tzm. These data were then c
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
