New modes in the terahertz spectrum of D-glutamine have been found in the first low-temperature measurements. With a high-purity sample and temperatures as low as 6K, eight intrinsic absorptions of D-glutamine in the frequency range below 4 THz have been identified. Tracking the frequency of the modes with temperature reveals anomalous blueshifting indicative of complex intermolecular hydrogen bond dynamics.
