Question
"You are reviewing two competing novel Force Fields, FFA & FFB, both describing Van Der Waals interaction between Hydrogen Atoms according to the Lennard Jones model. Both groups agree the Van Der Waals radius of the hydrogen atom as 1.2. The disagreement is in the value for sigma (for the Lennard Jones for E(r): sigma FFA: 2.337 A, sigma FFB: 2.137 A. Justify, what force field FFA or FFB is the most physically accurate? Thanks for any feedback/help! [5 pts] You are reviewing two competing novel Force Fields, FFA and FF8p, both describing the Van der Waals interactions between hydrogen atoms according to the Lennard-Jones model. Both groups agree on the Van der Waals radius of the hydrogen atom as 1.200 A (commonly accepted) The disagreement is in the value for (for LJ formula for E(r)): (EEAal-2.337A; gEEBAE2.137A. Justify, what Force Field, FFAa or FFBB, is the most physically accurate?Explanation / Answer
The closest is FFA: because it is closest to the FFB 2,337: 2,137
sigma FFA: 2,337 A is more accurate and correct.
