“…93–95 From there it was expanded to analytical applications and with the advent of ESI (and other desorption/ionization methods), tandem MS served in the rapid sequencing of biopolymers. 28,35,37,96 In the meantime it became also a very valuable method in inorganic chemistry for the identification of clusters 97,98 and in organometallic chemistry, where it can be a useful tool in the identification of reaction and decay pathways of catalysts. 99,100 Analogously, this method is often used in bioinorganic chemistry for the analysis of enzyme models.…”
