This relationship is undoubtedly responsible for much of the intensive theoretical and experimental investigation currently being carried out on these systems. The purely theoretical aspects of the relationship were recently discussed in detail by Zahradnik in a review on the Electronic Structure of Heterocyclic Sulfur Compounds, published in Volume 5 of this series.1...
