Reactions useful for the conversion of light energy into chemical energy are often complex because they require multiple charge transfer steps. Coupling electron and proton transfer facilitates these reactions by avoiding the high-energy intermediates found if electrons and protons are transferred individually and by enabling multiple charge transfer steps at one location. Our lab seeks to understand the types of chemical structures and environments that promote concerted electron/proton transfer by studying how ion structure changes in going from the ground state to electronically excited states. To accomplish these studies our lab works at the intersection between mass spectrometry and laser spectroscopy. We develop custom instrumentation to generate and trap ions and ion-molecule complexes, control their temperature, and then interrogate them by various types of spectroscopy.
