The quantum mechanical description of the electronic mo tion at each molecular geometry involves the response of each electron to the average field of all other elec trons and the approximate correlated response of each electron to the instantaneous position of the other elec trons. The basic methodology for the computation of this wave function, using extensive orbital basis sets and large-scale configuration expansions, is described. This calculation is one of the largest ever attempted for the characterization of a polyatomic reaction path. However, the path description involves a fine balance of energy contributions that requires this level of sophistication. The calculated properties of the reactants, the interme diate CH<jats:sub>3<\/jats:sub>, and the reaction paths to form CH<jats:sub>3<\/jats:sub> are pre sented. The computed energetics compare favorably to experimental results. <\/jats:p>","DOI":"10.1177\/109434209100500105","type":"journal-article","created":{"date-parts":[[2007,3,18]],"date-time":"2007-03-18T05:39:00Z","timestamp":1174196340000},"page":"72-89","source":"Crossref","is-referenced-by-count":6,"title":["An Ab Initio Theoretical Study of the CH + H2 \u21cc Ch3 * \u21cc Ch2 + H Reactions"],"prefix":"10.1177","volume":"5","author":[{"given":"Mutsumi","family":"Aoyagi","sequence":"first","affiliation":[{"name":"ARGONNE NATIONAL LABORATORY ARGONNE, ILLINOIS 60439"}]},{"given":"Ron","family":"Shepard","sequence":"additional","affiliation":[{"name":"ARGONNE NATIONAL LABORATORY ARGONNE, ILLINOIS 60439"}]},{"given":"Albert F.","family":"Wagner","sequence":"additional","affiliation":[{"name":"ARGONNE NATIONAL LABORATORY ARGONNE, ILLINOIS 60439"}]}],"member":"179","published-online":{"date-parts":[[1991,3,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1063\/1.443797"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1021\/j100308a039"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1021\/j100371a002"},{"key":"atypb4","first-page":"63","volume":"77","author":"Bauschlicher, C.","year":"1990","journal-title":"Chem.
