(a) XEOL spectra from crystalline amino acids in DMSO. The histidine and tyrosine spectra have been scaled down by factors of two and ten, respectively, in order to allow direct comparison of spectra from all of the samples. (b) Raw XEOL spectra from crystalline proteins highlighting the magnitude of the effect with respect to noise and the need to filter high-frequency noise prior to data analysis. Thermolysin data were collected on I24 at DLS; all other data were collected on X10SA at SLS. |
