WebbThe Hirshfeld procedure produces atomic charges that possess rather small magnitudes. At the HF/6-31 IG level of theory, the values of Qa are 0.14 for C in CO and 0.63 fw Li … WebbIn addition, Hirshfeld surface analysis and molecular docking simulations were executed on the target compound. ... The atomic charge distribution of the target oximino ester 5 is presented in Figure 3. C2 is the most positive atom owing to its connection to two electronegative oxygen atoms, ...
Webb8 juli 2024 · Hirshfeld charges obtained using more recent versions of Gaussian 09 (for example, Revision C.01 or D.01) may differ by a few percent, which should not be an issue in terms of the overall accuracy of the CM5 model. The directory Tests contains output files with CM5 and Hirshfeld charges obtained using Revision A.02, Revision C.01, and … Webb1 Hirshfeld atomic charges tend to be virtually zero.It can be argued that because there is no unique charge definition, the exact charges of AIM are unknown. However, nearly all other charge schemes give signifi-cantly larger atomic charges than the Hirshfeld scheme and there appears to be a consensus that Hirshfeld charges are too small.
