Towards enantiomer-specific spectroscopy and control of cold, chiral molecules — •Ju Hyeon Lee, Johannes Bischoff, A. O. Hernandez-Castillo, Marco De Pas, Gerard Meijer, and Sandra Eibenberger-Arias — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany

Chiral molecules are of paramount importance in the activity of biological molecules. Even though chemical and biological functionalities of different enantiomers are significantly different, their energy levels are equal, making detecting and quantifying them challenging. Therefore, there is a need for fast and reliable methods that can differentiate and/or separate enantiomers. Recently, the enantiomer-specific state transfer (ESST) method was developed where three mutually orthogonally polarized, resonant, phase-controlled microwave pulses are used to drive connected rotational transitions, resulting in controlled, enantiomer-specific population transfer [1]. We recently designed, built, and characterized a compact spectroscopy setup. It is capable of performing experiments in the 2-25 GHz regime, making studies of a large variety of molecules possible. Furthermore, our setup is equipped with a time-of-flight (TOF) mass spectrometer, and we implemented a combination of optical methods and microwave spectroscopy. Here we present preliminary results towards ESST of chiral molecules that are relatively rigid and simple, and have an aromatic ring, for example: 1-indanol.
