摘要
We present two range-separated (screened and long-range-corrected) extensions to our recent work on local hybrids of generalized gradient approximation exchange. Our screened local hybrid improves over HSE06 for thermochemistry and barrier heights. The long-range-corrected (LC) local hybrid improves over LC-omega PBE for heats of formation and nonhydrogen transfer reaction barriers but does not reach the accuracy of LC-omega PBE for hydrogen transfer barrier heights.
