AIP Conference Proceedings, Vol. 1323, n. 1, pág. 191-2002 (2010)0094-243X1551-7616 (electrónico)http://hdl.handle.net/10272/9782In this work we propose a symmetry projection approach to build a rovibrational basis for methane. In our method, symmetry adapted functions are obtained by simultaneous diagonalization of a set of commuting operators, whose representation is given in terms of direct products of Wigner’s D functions and vibrational matrix representations provided by a local scheme. The proposed approach is general and permits to obtain in a systematic fashion an orthonormal set of symmetry-projected functions, with good total angular momentum, and carrying the irreducible representations of the molecular symmetry group.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/MethaneSymmetry projectionRovibrational functionsjournal article10.1063/1.3537847open access
