Infrared spectroscopy of N2 adsorption on size selected cobalt cluster cations in isolation

Author affiliations

Abstract

We report IR active N2 stretching frequencies in isolated and size selected cobalt cluster nitrogen adsorbate complexes, [Con(N2)1]+ as recorded by virtue of InfraRed Photon Dissociation (IRPD) spectroscopy. The observed frequencies of the [Con(N2)1]+ complexes (n = 8–17) are significantly redshifted (2180 to 2290 cm−1) with respect to the IR inactive vibrations of free N2 (2359 cm−1). These bands are assigned to a μ1 head-on type of coordination of the N2 to the cobalt cluster surface, revealing remarkable cluster size dependent features to interpret.
