Large, Mode-Selective Vibrational Effect on the Reaction of C2H2+ with Methane
The reaction of C2H2+ with CH4 is strongly enhanced by excitation of a C2H2+ bending vibration, with little effect observed for the CC stretch. The enhancement results from efficient use of bending motion in surmounting an activation barrier Energy in the CC stretch has little effect on the threshold.
