Organometallics are widely used in catalysis and synthesis. Their analysis relies heavily on mass spectrometric methods, among which traveling-wave ion mobility spectrometry (TWIMS) has gained increasing importance. Collision cross sections (CCS) obt

Formation of the O-O bond is considered the critical step in oxidative water cleavage to produce dioxygen. High-valent metal complexes with terminal oxo (oxido) ligands are commonly regarded as instrumental for oxygen evolution, but direct experiment

N-Heterocyclic carbenes (NHCs, :C) can interact with azolium salts (C-H+ ) by either forming a hydrogen-bonded aggregate (CHC+ ) or a covalent C-C bond (CCH+ ). In this study, the intramolecular NHC-azolium salt interactions of aromatic imidazolin-2-

The thermal gas-phase reactions of [CeON]+ with methane have been explored by FT-ICR mass spectrometry and high-level quantum-chemical calculations. Nitrogen-atom transfer from the cluster ion to methane was observed as the only reaction channel. Bas
