title: Ab initio based DMBE potential energy surface for the ground electronic state of the C(2)H molecule.
abstract: We report a single-sheeted potential energy surface for the lowest state of C(2)H using double many-body expansion theory and accurate ab initio data points calculated at MRCI/AVQZ level of theory. The topographical features of the new global potential energy surface are analyzed in detail.
