Abstract: | Infrared and Raman spectra were obtained for 1,4-diiodobutane, and normal-coordinate calculations were made using a transferred 48-parameter modified v force field. This compound sometimes crystallizes in the GG' conformation with C2 symmetry and sometimes in the TG conformation. No evidence was obtained for the presence of the TT (C2h symmetry) or GG (Ci) conformers, but one or two additional conformers are present that must have a nonplanar chain of carbon atoms. |
