Due to the complexity of the internal energy structure of molecular ions, control of their quantum state poses serious challenges. Contrary to atomic counterparts, most molecules lack cycling optical transitions, which prevents standard state preparation and detection techniques based on optical pumping as well as direct translational cooling schemes. These challenging problems were recently...
Our group studies the complex rovibrational structure of trapped molecular ions. These states are often inaccessible by standard quantum information readout methods, but can be explored by co-trapping them with an atomic ion for which a convenient cooling and qubit level scheme exists. The molecular states can then be coupled to an electronic state of the atomic ion via quantum logic...
Analyzing biomolecular structures and spectra in the gas phase is challenging due to the large mass and intricate structures. Research frequently concentrates on selectively sampling specific biomolecules to gain insights into the broader system’s structure. This focused approach, rather than studying the entire system indiscriminately, provides valuable information about the behavior of the...
Photodetachment spectroscopy is a powerful spectroscopic technique for determining the internal state distribution of a molecular anion. Previously, our group studied the threshold photodetachment spectroscopy of CN$^−$ at both 16 K and 295 K in a 22-pole ion trap and measured the electron affinity of CN with great precision (EA: 3.864(2) eV) [1]. Here we present the threshold photodetachment...
Infrared spectroscopy is an important tool to probe inter-molecular and
intra-molecular motions as it is sensitive to the details of inter-molecular interactions. In the present study, we use this tool to explore structure and dynamics of super-critical water (SCW) across the Widom line (i.e. by varying density at a constant temperature
just above the gas-liquid critical temperature of the...
