A study was conducted to gauge various electronic structure methods, in particular density functionals of the generalized gradient approximation (GGA) type. The plane wave/pseudopotential data based on the Becke-Perdew ("P86") gradient-corrected density functional were compared to HF, MP2, QCISD/QCISD(T) as well as B3LYP results concerning both structures and energetics. Finally, the resulting data was analyzed in detail.
