WebDec 1, 2024 · exponentially. Dispersion corrections are important for the present calculations because of weak van der Waals forces between the interacting molecules. GD3BJ dispersion correction version are added [31]. Vibrational Raman shifts are calculated with the use of the usual scale factor of 0.962 suitable for the kind of used … WebThe proposed corrections differ in the form of the damping function f(R) and the atom-atom dispersion coefficients Cn. In this work, we focus on the empirical –f(R)C6/R 6 correction to DFT methods recently proposed by Grimme3, 4 for molecular systems. Grimme defined a general set of parameters and used an optimized scaling factor to adjust the
