Since lifetimes of vibrationally excited adsorbates are often significant, the probability of an ER reaction followed by vibrational excitation and subsequently by dissociation might be significant. 5.2 Polyatomic Adsorbates Figure 4 depicts the PES intersection for H(g) + CH* at Ni(111) along the fcc-top-hcp line, while Figure S.9 shows the PES along the fcc-bridge-hcp line, which shows a similar profile.
