Understanding the reaction between muonium atoms and hydrogen molecules: zero point energy, tunnelling, and vibrational adiabaticity

摘要: The advent of very precise measurements rate coefficients in reactions muonium (Mu), the lightest hydrogen isotope, with H2 its ground and first vibrational state kinetic isotope effects respect to heavier isotopes has triggered a renewed interests field muonic chemistry. aim present article is review most recent results about dynamics mechanism reaction Mu+H2 shed light on importance quantum such as tunnelling, preservation zero point energy, adiabaticity. In addition accurate mechanical (QM) calculations, quasiclassical trajectories (QCT) have been run order check reliability this method for isotopic variant. It found that H2(v=0) dominated by high energy (ZPE) products tunnelling largely irrelevant. Accordingly, both QCT calculations preserve products’ ZPE well those based Ring ...
