Abstract
The values and signs of ^13^C, ^1^H spin‐spin coupling constants in 1,6,6aλ^4^‐trithiapentalene and 1,6‐dioxa‐6aλ^4^‐thiapentalene have been re‐investigated. The contributions from second order effects in the spectra have been included in an iterative spectral analysis. The values found deviate significantly from the values found earlier by first order analysis. The signs of the spin‐spin coupling constants have been established by the use of the SPT technique.
