Figure 1: Comparison of CQ cores, without and with the attached reversal agent (making RCQ_02; see below). The CQ portion of each molecule ranges from an electrostatic potential of 0(green) to –0.2(red), mapped on density = 0.002 electronic surface. Much of the remainder has positive electrostatic potentials in blue. The electrostatic densities and potentials of the CQ portions of these molecules are nearly identical.
