High-temperature photochemistry study of the D + ND/sub 3/ reaction
Technical Report
·
OSTI ID:7159764
The kinetics of the D + ND/sub 3/ reaction was studied from 590 to 1220 K by using the high-temperature photochemistry (HTP) technique. D(12S) atoms were generated by flash photolysis of ND/sub 3/ and monitored by time-resolved atomic resonance fluorescence with pulse counting. K2(T) is determined to be exp(-8810 K/T) cc/molecule/s. Accuracy assessments are discussed in the text. Comparison to k1(T) for H + NH/sub 3/(1) measured in the same apparatus and over a similar temperature range shows that k2(T) is smaller. K1(T) and k2(T) agree reasonably well with calculations based on transition-state theory and a simple tunneling model using the same potential energy surface for both reactions. Considered alone, K2(T) can also be modeled without tunneling.
