報告題目： Non-covalent interactions studied by mass-resolved ZEKE spectroscopy: the future 報告人： Prof. Klaus Müller-Dethlefs Founding Director of The Photon Science Institute and School of Chemistry The University of Manchester，United Kingdom 報告時間：八月三十日（星期五）上午10:30 報告地點：理科樓三樓報告廳摘要： we are reviewing the ZEKE method and its mass-selective variant, Mass Analysed Threshold Ionisation, MATI, in order to measure dissociation energies of molecular clusters with spectroscopic precision. In the near future, our studies will be extended to the systematic measurement of non-covalent stacking interactions in polycyclic aromatic dimers up to the coronene-dimer, a nano-graphene analog. This will be accompanied by high-level computations using coupled-cluster expansion theory up to CCSDT(Q). The goal is to establish benchmarks for the reliable application of ab initio calculations to very rage non-covalently bound supramolecular systems.
