NMR Studies of Equilibrium Quotient of the Benzonitrile with Xylene Isomers and Ethylbenzene

Abstract

<em>The charge transfer (CT) complex formation of benzonitrile as acceptor with the aromatic donors o-, m-, p-xylene and ethylbenzene in CCl₄ solutions is investigated by chemical shift measurements relative to an external reference. The equilibrium parameters, </em><em>Q</em><em> and </em><em>D</em><em>_AD</em><em> of their weak molecular complexes, as found numerically modified Cresswel- Allred (C-A) method, is compared with graphically Scatchard-Foster-Fyfe (Sc-F-F) method.</em>
