Generation of HCl, DCl, HBr, and DBr

Rate constants and products for the reaction of HBr ÷ with HBr and DBr

The proton transfer channel for the reaction of HBr + with HBr is investigated in a state-specific manner by preparing the reagent ion in a selected internal state by resonance-enhanced ionization (REMPI) and monitoring the disappearance of this ion by laser-induced fluorescence (LIF). A rate constant for proton transfer of (6.7 + 1.6) × 10-10 cm3/s is found. The reaction of HBr + with HBr and ...

Chemical reactivity of ultracold polar molecules: investigation of H + HCl and H + DCl collisions

Quantum scattering calculations are reported for the H + HCl(v, j = 0) and H + DCl(v, j = 0) collisions for vibrational levels v = 0− 2 of the diatoms. Calculations were performed for incident kinetic energies in the range 10 − 10 eV, for total angular momentum J = 0 and s-wave scattering in the entrance channel of the collisions. Cross sections and rate coefficients are characterized by resona...

Rate of water vapor evaporation from ice substrates in the presence of HCl and HBr

Using a multidiagnostic approach the rate R ev or flux J ev of evaporation of H 2 O and its condensation, k cond , on a 1µm thick ice film have been studied in the temperature range 190 to 240 K as well as in the presence of small amounts of HCl and HBr that left the vapor pressure of H 2 O on ice unchanged.
