Article on a computational study of the enthalpies of formation of halomethylidynes.
Physical Description
5 p.
Notes
Abstract: The halomethylidynes CH, CF, CCI, CBr, and Cl have been investigated using GAUSSIAN-2 theory and calculations up to QCISD(T)/6-311 + G(3df,2p). At the latter level of theory bond lengths, harmonic frequencies, and anharmonicity corrections have been derived and compare well with experimental measurements where these are available. GAUSSIAN-2 and QCISD(T)/6-311 + G(3df,2p) energies were employed in isodesmic reactions to obtain the following recommended enthalpies of formation (∆fH(298)) in kJ mol(-1) : CF, 248.6; CCl, 436.9; CBr, 497.1; Cl, 557.6. Estimated error limits are ± 6 kJ mol(-1).
