C2H2CO complex. Ab initio calculations with the coupled-cluster method and first-order correlation orbitals

Research output: Contribution to journalArticle

Three equilibrium conformers are identified for the C2H2CO complex. Coupled-cluster calculations with the first-order correlation orbitals indicate that the two linear structures, i.e. carbon- and oxygen-bonded, are isoenergetic and should coexist in the gas phase. However, due to smaller internal flexibility, the carbon-bonded complex should have a more definite structure.
