What is it about?
This work indicates that the splitting of the nitrate v3 mode in aqueous solution most likely arises from a lowering of the symmetry due to an interaction with the local environment. Rotational motions of the ion acting on top of this splitting then produce the observed differences in band centres between infrared and Raman spectra and are responsible for the width of the band. It would be informative to compute the rotational-vibrational bands of say a C2v nitrate ion.
