The 13 C NMR spectra of forty‐six cyclic dithioacetals and their derivatives have been studied. A set of shift parameters was established for each of these heterocycles as substituent. Based on the Hammett type correlation for substituted benzenes, the σ P + values of cyclic dithioacetal groups have been determined.
