************ The 13st Lab Seminar ************* Title : Communications: A systematic method for locating transition structures of A + B -> X type reactions (JCP, 132, 241102 (2010)) Speaker : Norio Takenaka Date : Tue. Feb. 7th, 1:30 pm Search for transition structures (TSs) as first-order saddles is one of the most important tasks in theoretical study of chemical reaction. Although automated search has been established either by starting from a local minimum (MIN) or by connecting two MINs, there is no systematic method which can locate TSs of A + B -> X (+Y) type reactions starting from separated reactants. We propose such an approach for the first time; it was demonstrated to work very well in the SN2, Diels?Alder, and Wittig reactions. ***********************************************************
