Abstract

Abstract We have investigated the adsorption of nitrogen on Cr(110) at 100 K and have found strong evidence to support the existence for a weakly bound molecular state. We estimate that the heat of desorption for this molecular nitrogen state from Cr(110) is approximately 14 kJ/mol. Desorption from this state is completed by 155 K. This molecular nitrogen species is believed to be coadsorbed or is identical to the α-nitrogen state observed by previous photoemission studies.
