Vibrational Assignments in Small Molecules,ecules having only three or four atoms and for some larger molecules if they possess sufficient symmetry. However, the complexity of the spectrum increases rapidly with each added atom, and unequivocal assignments are still sought for some molecules with as few as four and five atoms.

Interferometry: Experimental Techniques and Applications to Inorganic Structures,ely recently, experimental difficulties have prevented the determination of all the information which is, in principle, available from infrared and Raman spectra.
