Popis:	An experimental and theoretical study of the UV absorption spectra of bithiophens indicates that non planar conformations are predominant in vapour phase and non polar solutions. The existence of steric strain within dibramobithiophens induces an increase of the twist angle. An evaluation of this angle is carried out for each compound.
