Dear all,
Can MD simulation be used to radical system? We are going to check the water distribution around a radical molecule. Are the atomic charges obtained as the neutral molecule for radical?
As in the following example, should the electron pair on C4 atom be restraint during RESP calculation?
e.g.
REMARK
REMARK
ATOM 1 C1 MOL 1 -3.428 1.900 -0.002 1.00 0.00
ATOM 2 C2 MOL 1 -2.207 1.365 0.000 1.00 0.00
ATOM 3 N3 MOL 1 -2.383 0.036 0.001 1.00 0.00
ATOM 4 C4 MOL 1 -3.668 -0.267 -0.001 1.00 0.00
