Hey
Im doing vibrational spectroscopy (Raman, nir, vis/uv) of a protein called C-reactive Protein. Its a symmetric molecule regarding the subunits
http://en.wikipedia.org/wiki/C-reactive_proteinThen i wondered if one can apply normal coordinate analysis (using symmetry and group theory) to the molecule? does this make sense? will it give any information about forces between the subunits? or am I wrong?
