Figure 3: Influence of concentration on the OKE spectra of cytidine monophosphate.
From: Observation of coherent delocalized phonon-like modes in DNA under physiological conditions

The terahertz band of the spectra has been fitted using two Brownian oscillators at 1.48 and 2.58 THz (top). The effect of the concentration on the intensity of these bands (blue and red, respectively) has been plotted (bottom).
