Keywords: adsorbate; carbene; current-induced heating and cooling; molecular junction; vibrations; Introduction Molecular electronics has experienced a remarkable progress since its first proposal [1]. Theoretical as well as experimental advances have made

• also quantify the direct role of NH2 states in vibron populations. We establish a connection between this change and the degree of localization of vibrational modes on the adsorbate. This work shows that adsorbate species in the vicinity of the junction can influence the current-induced heating and
