Experimental THz spectrum of the translation region of water in the 170–240 cm −1 spectral region of (a) the HHS and (b) the LHS of crambin at 93 K (blue solid line), 200 K (green dashed line), and 303 K (red dot-dash-dotted line). The labels of (1) and (2) in the spectra of (a) and (b) refer to distinct intermolecular structures [46] of water that we have assigned at specific frequencies in the experimental spectra.
