Quadrupole mass-filter sensitivities of H/sub 2/, HD, D/sub 2/, and T/sub 2/, and the kinetics of. beta. -particle induced exchange between H/sub 2/, D/sub 2/, and T/sub 2/ at 25. 4/sup 0/C (open access)

Quadrupole mass-filter sensitivities of H/sub 2/, HD, D/sub 2/, and T/sub 2/, and the kinetics of. beta. -particle induced exchange between H/sub 2/, D/sub 2/, and T/sub 2/ at 25. 4/sup 0/C

We have constructed a quadrupole-mass filter system to measure the equilibrium constants and rates of reaction of the ..beta..-particle-induced exchanges between H/sub 2/, D/sub 2/, and T/sub 2/ at cryogenic temperatures. Even with careful calibration experiments at 25.4/sup 0/C, we could not completely remove the mass discrimination inherent in our method. We estimate the accuracy of our mixture analyses to be +-2.2% in the D/sub 2/-DT-T/sub 2/ system, and +-9% in the H/sub 2/-HT-T/sub 2/ system. Preliminary kinetic experiments showed that the time to reach equilibrium in the exchange H/sub 2/ + T/sub 2/ = 2HT is 7 to 14 h. The equivalent time interval in the exchange D/sub 2/ + T/sub 2/ = 2DT is 3 to 7 h. This measured isotope effect of two can be used to predict the rates of the DT exchange from the HT rates in the literature.
