Rotational-state distribution and ortho-para conversion of molecularly chemisorbed H $_{2}$ on Pd(210)

Ueta, Hirokazu ; Sasakawa, Yuya*; Ivanov, D.*; Ono, Satoshi*; Fukutani, Katsuyuki

While hydrogen typically chemisorbs dissociatively on a flat metal surface, it is known that hydrogen can molecularly chemisorb on stepped surfaces, such as Pd(210). In this study, using a combination of a pulsed molecular beam, photo-stimulated desorption and resonance-enhanced multiphoton ionization techniques, the rotational states of molecularly chemisorbed H $_{2}$ are probed. We will present the rotational state distribution of photo-desorbed H $_{2}$ , and the o-p conversion process of molecularly chemisorbed H $_{2}$ will be discussed.
