This book demonstrates  how quantum tunnelling manifests itself into NMR  relaxometry, by taking methyl rotors as a model; As  temperature is decreased the continuous transition  from classic mechanics behaviour to quantum  tunnelling behaviour of methyl rotors is shown. A  potential energy source -- the tunnelling reservior  of methyl rotors is investigated and the rate of the  energy release to lattice is measured. To achieve  the experiments a state-of-the-art NMR technique  called the field cycling NMR relaxometry is  implemented, and this technique is also discussed in  this book.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838391403\"\u003e\u003ch3\u003eA Quantum Mechanics Sutdy by Field Cycling NMR\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838391403","offer_id":39499016536157,"sku":"9783838391403","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/611b613b-6011-4b7b-9e3d-6c1a89893396.jpg?v=1770790678","url":"https:\/\/shop.autorenwelt.de\/en\/products\/quantum-dynamics-and-tunnelling-of-methyl-rotors-von-cheng-sun","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
