Electronic structure, vibrational frequencies, and ¹H chemical shifts of inclusion complexes between CB[n] (n = 6,7) or their inverted iCB[n] diastereomer hosts and quaternary diammonium viz., 1,6-hexyldiammonium (HDA) or p-xylyldiammonium (XYL) cationic guests are obtained from the density functional calculations. The interaction of CB[n] or iCB[n] with HDA (guest) conduce inclusion complexes ...
