TLDR: In this paper, the authors studied nitrogen and chlorine pure quadrupole resonance spectra in some charge transfer complexes with a chloroform molecule as acceptor, the donors being some amino and heterocyclic compounds.

Abstract: We have studied nitrogen and chlorine pure quadrupole resonance spectra in some charge transfer complexes with a chloroform molecule as acceptor, the donors being some amino and heterocyclic compounds. A discussion of the present results and consideration of previous data confirm the charge transfer in these complexes. From the observed frequency shifts with respect to the uncomplexed compounds, the charge transfer can be estimated to a few per cent of an electron charge. Nous avons etudie la resonance quadripolaire pure de l'azote et du chlore dans quelques complexes a transfert de charge. L'accepteur y est le chloroforme, tandis que les donneurs y sont des amines ou des heterocycles. La discussion des resultats obtenus, compte tenu de donnees anterieures, semble confirmer le transfert de charge dans ces complexes. L'estimation du transfert, a partir des deplacements de frequence mesures, fournit une valeur egale a quelques centiemes de la charge electronique.
