Addition of two water molecules allows the H-bond formation with all four NH3 + groups of porphyrin, although these bonds are not equal; this is proved by difference in the NBO partial charges of orthocarbons of up to 0.12 between phenyls with the H-bonded NH3 + groups. In α2β2-Pꞏ10CSA(R), the larger size of camphorsulfonic acid allows the H-bond formation with all four NH3 + groups of porphyrin; however non-equality of the formed bonds results in differences between the NBO partial charges of orthocarbons of up to 0.13.
