The analysis of the 1H NMR spectra of 2,8-dithia-1,5-diphosphabicyclo[3.3.0]octane, 2,8-dithia-1-phospha-5-azabicyclo[3.3.0]octane and 2,8-dithia-1-arsa-5-phosphabicyclo[3.3.0]octane is supported by means of 2D- J-resolved NMR measurements. The spectra suggest a preferred conformer with strong puckering of the fused five membered rings.
