The ESR spectra of the cation radicals of TTF and its related compounds in which two 1,3-dithiole rings are connected by conjugated carbon and cumulene chains are measured. The spin distributions obtained from the <I>hfcc</I> due to the protons and sulfur atoms agree well with the results of the MINDO/3 calculations. The spin densities on the sulfur and central carbon atoms decreases as the central chain length increases. A linear relationship, <I>g</I>=2.00379+0.00108 <I>a</I>(<I>S</I>), between the <I>g</I>-values and the sulfur <I>hfcc</I> is noted and explained in terms of the Stone's theory. The <I>g</I>-values of the cation radicals with cumulene chains deviate from this relation and a possible cause is suggested.
