Fig. 2: (Non)reactive trajectories under vibrational strong-coupling.

Exemplary trajectory outside g0/ℏωc = 0 (black), inside the cavity on resonance g0/ℏωc = 1.132, ωc = 856 cm−1 (orange) and off-resonant g0/ℏωc = 1.132, ωc = 1712 cm−1 (red) undergoing the reaction illustrated in Fig. 1b, c. The transition-state is indicated with a yellow star. Encoded in the transparency is the relative angle between Si-C and cavity polarization axis (inset Fig. 1d). The molecular axis remains largely oriented along the cavity polarization during the reaction.
