Dear VMDers,
I have an atomistic model (pdb file), which is an isotactic polymer chain. From the visualized model in VMD, I can tell the tacticity. However, how to characterize the tacticity using some geometric parameters (i.e., bond angles, dihedral angles)? And how to change the tacticity from isotactic to syndiotactic by some geometric operations? Thanks a lot for any reply to this letter.
Yours sincerely,
Chaofu Wu
