Experimental and Computational Investigation of the Bond Energy of Thorium Dicarbonyl Cation and Theoretical Elucidation of Its Isomerization Mechanism to the Thermodynamically Most Stable Isomer, Thorium Oxide Ketenylidene Cation, OTh+CCO

Collision-induced dissociation (CID) of [Th,2C,2O]+ with Xe is performed using a guided ion beam tandem mass spectrometer (GIBMS). The only products observed are ThCO+ and Th+ by sequential loss of...

Evaluation of the Pr + O → PrO+ + e− chemi-ionization reaction enthalpy and praseodymium oxide, carbide, dioxide, and carbonyl cation bond energies

Guided ion beam tandem mass spectrometry was used to measure the kinetic energy dependent product ion cross sections for reactions of the lanthanide metal praseodymium cation (Pr+) with O2, CO2, and CO and reactions of PrO+ with CO, O2, and Xe.
