The vibrational spectra of water contain signals arising out of all three vibrational modes, namely, O-H symmetric stretching (ν1), H-O-H bending (ν2) and O-H antisymmetric stretching (ν3). But, the spectral line shape is not necessarily a straightforward manifestation of these vibrational modes. Rather, the vibrational signals of water arise as a result of a complex interplay of various factors, with hydrogen-bonding and intra-/intermolecular coupling of the normal modes playing important roles, as is the case for any vibrational spectrum of water. This study is centred around the broad O-H stretching band that a Raman spectrum of liquid water contains as the most prominent feature. It remains a matter of debate to assign overlapping peaks that constitute the 2700-3900 cm -1 O-H stretching signal to specific origin. This is why, often water Raman spectra are deconvoluted to multiple peaks and the deconvoluted peaks are assigned in a series from lower to higher frequency gradually to the vibrational response of O-H bonds in tetrahedrally hydrogenbonded water molecules, i.e., water molecules with four hydrogen-bonds, to non-hydrogen-bonded O-H bonds in water. From this perspective, the peak around 3250 cm -1 arises due to contribution from fully hydrogen-bonded water molecules, the peak around 3420 cm -1 arises due to contribution from less or limited hydrogen-bonded water molecules and the shoulder at around 3610 cm -1 arises due to contribution from O-H bonds that participate in very little hydrogen-bonding, perhaps just fleetingly.
