In this work, 242 NMR spin–spin coupling constants (SSCC) in 20 molecules are calculated, either with correlated wave function methods, SOPPA and HRPA(D), or with density functional theory based on the B3LYP, BHandH, or PBE0 functionals. The calcul

Efficient implementation of the priority order

Autor: Žanić, Mislav

U ovom smo radu prezentirali dvije asimptotski efikasne implementacije prioritetnog reda. U prvom smo poglavlju dali definiciju prioritetnog reda. Također, naveli smo i neke dodatne definicije koje smo koristili kroz ovaj rad. U drugom poglavlju bav

The performance of different polarization propagator methods, such as RPA, RPA(D), HRPA, HRPA(D), and SOPPA, have been tested against CC3 values for both static and dynamic polarizabilities. The test set consists of 14 (hetero-)aromatic medium-sized

The second‐order noniterative doubles‐corrected random phase approximation (RPA) method has been extended to triplet excitation energies and the doubles‐corrected higher RPA method as well as a shifted version for calculating singlet and triple
