The H 2 + OH → H 2 O + H reaction plays a crucial role in combustion, especially in hydrogen combustion, as well as in atmospheric chemistry. To date, no resonance signature has been detected in this reaction or its isotopic analogues for the initial ground state . However, our recent studies on the reverse reaction H + HOD → H 2 + OD have revealed pronounced oscillatory structures in the total reaction probabilities and integral cross sections (ICS) at low collision energies, when the reagent HOD is vibrationally excited to v OH =3 and 4. Analysis of the scattering wave functions revealed that these oscillations originate from the Feshbach resonance states trapped in the bending/torsion excited vibrational adiabatic potential (VAP) wells in the entrance region due to van der Waals interaction. The product angular distributions exhibit a forward-backward peaked behavior at these energies, attributed to the long lifetimes of these resonances. Now, a key question of interest is whether resonance phenomena exist in the vibrational excitation reaction of H 2 + OD and whether their origin is similar to that observed in the reverse reaction.
