Spin-restricted
ensemble-referenced Kohn–Sham (REKS) calculations have been performed on isomeric benzyne systems. The density functional results compare favorably with those of multi-reference CASPT2 and CASRS3 methods.
In general for enthalpies of isodesmic reactions, the REKS energies are in better agreement with experiment
compared with the ab initio
calculations. Experimental singlet–triplet
energy
gaps are reproduced
to within 1 kcal mol−1 of experimental values.
