Spectroscopic and theoretical studies of 3,3,6,6-tetramethyl-1,2,4,5-tetroxane are presented. Molecular dynamics calculations were performed to scan the conformational space of the molecule. Density functional calculations were carried out on the stable conformers to obtain a better description of m
study ( < -30"C)1111. This is best evidenced by the upfield shift of protons H' (by 23Hz) and H5 (by 32Hz) on going from ( 3 ) to ( 5 ) , which simply reflects the increased availability of the lone pair for limited delocalization but is clearly inconsistent with the development of the diamagnetic r
