Stable and less stable conformers of fluorobutadienes: an ab initio SCF MO study Abstract Ab initio SCF-MO calculations at the 3–21G F* level with full geometry optimization were performed for cis-1-, trans-1- and 2-fluoro-1, 3-butadiene.The critical points for the rotation around the central CC bond are located and discussed. Trans-1-fluoro-butadiene has a stable gauche from…
