Vibrational frequencies and structural determination of norbornadiene

The vibrational frequencies and corresponding normal mode assignments of norbornadiene are examined theoretically using the gaussian98 set of quantum chemistry codes. All normal modes were successfully assigned to one five types of motion predicted by a group theoretical analysis (CC stretch, C-C stretch, C-H stretch, C-H bend, and C-C-C bend) utilizing the C2v symmetry of the molecule.
