Infrared spectrum of divinyl telluride and theoretical analysis of divinyl group VI compounds

The infrared spectrum of divinyl telluride (DVT) has been studied for the gaseous, liquid and solid phases as well as in inert matrices at low temperatures. HF-SCF calculations (using triple-zeta quality basis sets) have been carried out on DVT and on the oxygen, sulfur and selenium analogs. In each instance the calculations predict two relatively stable conformations, with the cis/trans form being the more stable for divinyl ether and a near-planar trans/trans form being the more stable for the other three compounds. The infrared spectrum of DVT is consistent with the presence of two rotameric forms of the molecule, and assignments of many of the absorptions are made to normal modes. © 1995.
