High-resolution ^(13)C pulse Fourier transform nuclear magnetic resonance has been used to study the effects of charge-transfer complexation between trinitrobenzene and aromatic donor molecules: benzene, mesitylene, naphthalene, and anthracene. Plots of the chemical shifts of the donor carbons as a function of acceptor concentration allows the ready determination of the association constants, K_(AD), and the bound shifts of the donor carbons in the pure 1:1 complexes, Δ_0. The Δ_0 values so obtained indicate that diamagnetic ring anisotropy and transfer of charge are as phenomenologically important to ^(13)C as to ^1H NMR for aromatic molecules.
