MEP of CHP1 to CHP5. For CHP1 MEP is represented from − 4.636 a.u. to + 4.636 a.u., for CHP2 it is from − 4.646 a.u. to + 4.646 a.u., for CHP3 from − 6.529 a.u. to + 6.529 a.u., for CHP4 from − 7.159 a.u. to + 7.159 a.u. and for CHP5 from − 5.104 a.u. to + 5.104 a.u. The most electron rich region for all compounds, except for CHP2, is located at N6 and for CHP2 it is O19. Furthermore, the least electron rich region for CHP1, CHP2 and CHP5 is at H11 but for CHP3 and CHP4 it is H26
