Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science and related areas. 17 The approach should be similar to TDDFT in that it was mostly of “black‐box” character. Start by selecting the Output file format (Cube format for example), then the grid interval (determines the resolution of. The "UKS" keyword calls for an unrestricted Kohn-Sham (DFT) Remembering that ORCA counts orbitals starting from 0 and also that our system contains 13 spin up (alpha) and 12 spin down (beta) electrons, this command interchanges the highest occupied beta orbital with the lowest unoccupied beta orbital. Ruhr, Germany [email protected] RI approximation was used. Spin contamination is often seen in unrestricted Hartree-Fock (UHF) calculations and unrestricted Møller-Plesset (UMP2, UMP3, UMP4) calculations.
