Abstract: The obtained vibrational spectra of ethyl halides do not seem to be explained on the basis of the possible symmetries ; Cs, C2 or C1 for rigid structures of ethyl halides. Considered as a rigid structure, a Cs symmetry is the highest one for C2H5- X(X=Cl, Br, I), for which the selection rules predict 18 fundamentals to be both in Raman and infrared active. A non-rigid structure in which CH2 group rotates freely with respect to the three hydrogen atoms of CH3 group, seems to be more reasonable for CH3-CH2-X. The selection rules derived from the non-rigid structure yield 8 fundamentals(4A1+4E) due to CH3-(Y)-X(Y=CH2)(C3v) and a few fundamentals due to the added CH2 group. The obtained spectra of ethyl halides can be explained on the basis of the selection rules for the above non-rigid molecule. In addition, the NMR specra of these compounds strongly suppot a non-rigid C3v model.
