## Abstract The hydrogen‐bonded charge transfer complexes of aniline with π‐acceptors (or proton donors) such as 2,5‐, 2,6‐, 3,4‐ and 3,5‐dichlorophenol were prepared. The ^35^Cl nuclear quadrupole resonance (NQR) frequencies of these charge transfer complexes in the temperature range 77–300 K were
