While a variety of compounds containing planar tetracoordinated carbon (ptC), the so-called anti-van’t Hoff/Le Bel carbon, are known experimentally, stable systems containing planar tetracoordinated s
Linearized Coupled Cluster Doubles (LinCCD) often provides near-singular energies in small-gap systems that exhibit static correlation. This has been attributed to the lack of quadratic T̂22 terms tha
