Most knowledge of molecular propagation is derived from the time-dependent Born-Oppenheimer approximation. This approximation breaks down at electron energy level crossings, which are prevalent in molecular systems. Hagedorn classifies generic, minimal multiplicity level crossings and derives a normal form for the electron Hamiltonian near each type of crossing. He then extends the time-dependent Born-Oppenheimer approximation to accommodate the propagation of nuclei through each type of electron energy level crossing.","brand":"American Mathematical Society","offers":[{"title":"Default Title","offer_id":53703098892630,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9780821826058_1_cfef652f-eb13-4cb2-9a64-ad3e10db2c36.jpg?v=1781758640","url":"https:\/\/www.momoxbooks.com\/products\/a-george-hagedorn-molecular-propagation-through-electron-energy-level-crossings-memoirs-of-the-american-mathematical-society-9780821826058","provider":"momoxbooks","version":"1.0","type":"link"}
