Dear amber users
We're studying organic systems like porphyrins and porphycenes. We need some
bond, angle and dihedral parameters for some substituents like -Cl and -NO2
bonded to an aromatic system. We'll appreciate your help if some of you have
some references or have developed those parameters.
Thanks in advance
