From: The fluctuating ribosome: thermal molecular dynamics characterized by neutron scattering

Quasi-elastic neutron scattering intensities, at 298 K, binned over the whole wave-vector range accessible on the IN5 spectrometer (0.2–2 Å−1) and normalized to unity.
Left panel: H30S-3 M NaCl (solid line) and H50S-3 M NaCl (dotted line), Right panel: – H30S-3 M NaCl (solid line) and H30S-3 M KCl (dashed line). Insets: same spectra at reference Q = 0.3 Å−1 (fluctuation amplitudes > 20 Å) and Q = 1.2 Å−1 (amplitudes ~5 Å). A broader intensity distribution indicates scattering from faster motions (see text).
