## 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
## Abstract One‐bond isotope shifts of ^35^Cl/^37^Cl natural abundance chlorine isotopomers were measured in the 75.4 MHz ^13^C NMR spectra of a series of __para__‐substituted chlorobenzenes. The high‐field isotope shift effect ^1^Δ^13^C(^37^Cl) was established from the relationship between the chl
