Intrinsic Gas-Phase Behavior Of Uranium Species: A Comprehensive Reactivity Study Of [O=U≡Ch]+ And [Uh]+, Justin Terhorst Dec 2024

Intrinsic Gas-Phase Behavior Of Uranium Species: A Comprehensive Reactivity Study Of [O=U≡Ch]+ And [Uh]+, Justin Terhorst

Electronic Theses and Dissertations

The intrinsic chemistry of actinide elements, particularly uranium, remains a key challenge in understanding f-block reactivity due to the complexity introduced by solvent interactions, counter-ions, and complex equilibria in the condensed phase. In this dissertation, a systematic gas-phase study utilizing preparative tandem ion-trap mass spectrometry (PTMSn) is presented, focusing on the reactivity of uranium-centered species, specifically [OUCH]+, an oxy uranium methylidyne species, and [UH]+ ions. By stripping away solvent effects and isolating the ions, PTMSn provides a powerful platform to probe the fundamental chemical behavior of uranium species in their intrinsic state.
