Spectroscopic Investigation of Molecules in Quantum Condensed Phases

Principal Investigator: 

Recently, we found that molecules in quantum condensed phases such as solid parahydrogen and superfluid He nano-droplets show completely quantized rotational energy levels, to which high-resolution spectroscopy can be applied. As a result, high-resolution spectroscopy of molecules in quantum condensed phases provides a powerful technique for detailed and precise investigation of their properties at the moderately low temperatures of 10 K - 0.1K. The research topics include investigation of intermolecular interactions, relaxation and decoherence processes, and chemical reaction dynamics at low temperatures-all of which are very difficult to obtain by other experimental techniques.
