Abstract The conformation of 1,2,4,5-tetrathian was determined by means of dynamic NMR spectroscopy. The barrier (ilG+) of the chair/twist equilibration is 14.5 kcal/mol and the chair form is more stable than the twist form in this molecule by 1.4 kcal/mol. These experimental data are in excellent agreement with force field calculations
