How is mp2 calculated
WebCorrelated calculations scale less favorably, though their accuracy is usually greater, which is the trade off one needs to consider. One popular method is Møller–Plesset perturbation theory (MP). To second order (MP2), MP scales as N4. To third order (MP3) MP scales as N6. To fourth order (MP4) MP scales as N7. Web15 jul. 2002 · The GIAO-MP2 method has been shown to give reliable results for 11 B NMR chemical shift calculations in H 3 BX (X = NH 3, PH 3, H 2 O, H 2 S, and CO) complexes . The calculated δ 13 C value of dicationic 1b is 15.2 (with respect to tetramethylsilane) and the calculated δ 11 B of cationic 1a is −16.5 (with respect to BF 3:OEt 2).
