The full-length (solid line) and truncated (dotted line) ASRL minus ASR spectra (pH 7) in the 1,800–900 cm-1 region. The spectra are measured at 170 K upon hydration with H2O. One division of the y-axis corresponds to 0.004 absorbance units. This figure is reprinted with permission from Kawanabe et al [77]. Copyright 2008 American Chemical Society.
