Abstract

Abstract : Dimeric and trimeric Au25 (SR)18 have been detected experimentally by electrospray ionization mass spectrometry (ESI MS) and separated by ion mobility (IM). Abstract : We present the first example of dimer formation in the monolayer protected atomically precise cluster system, Au25 (SR)18, using ion mobility mass spectrometry. These transient species are shown to be important in explaining chemical reactivity between clusters.
