Fig. 3.
Quasielastic neutron scattering spectra of lysozyme, tRNA and DNA (symbols); lines show the resolution function of spectrometers. Data for lysozyme and tRNA are from [7], for DNA from [20]. Lysozyme spectra exhibit relaxation contribution even in the dry state and at T = 200 K, while no quasielastic scattering is observed for dry tRNA and DNA, or for hydrated tRNA and DNA below 210 K
