Thermodynamic insight into AnO 2 + bonding from ThH + /UH + reactions studied by inductively coupled plasma tandem mass spectrometry

Key Points

• The research aims to investigate how bonding mechanisms vary between early and later actinides based on reaction enthalpies.
• Analyzed reaction enthalpies using inductively coupled plasma tandem mass spectrometry
• Studied reactions involving AnH+ and CO2 with a focus on AnO2+ formation
• Compared early and latter actinide elements in bonding mechanisms
• A shift in reaction enthalpy trends indicates possible differences in bonding mechanisms
• Later actinides show increased accessibility of 6d orbitals, affecting bonding behavior
• Findings suggest distinct chemical behaviors between early and later actinides
