Rate constants for the reactions C2H+ C2H2-. C4H2+ H and C2D+ C2D2-+ C4D2+ D have been measured over the temperature range 296-1475 and 1226-1700 K, respectively. For the high-temperature experiments, the method was the laser photolysis-shcck tube technique (LP-ST); however, for the room-temperature experiments, the laser photolysis- resonance absorption (LP-RA) technique was used. These techniques utilize the atomic ...
