Figure 2: (a) Second derivative spectra from 3000 to 2800 cm−1 of lysozyme in D2O solution. Red line represents the exposed sample spectrum, after 3 h of exposure to a magnetic field of 180 T. The increases of CH2 bands at 2921 and 2853 cm−1 are evidenced. (b) Second-derivative spectra from 3000 to 2800 cm−1 of lysozyme in trehalose D2O solution acquired after analogue exposure conditions. No appreciable difference can be observed with respect to not exposed sample’s spectrum. Red lines represent exposed sample spectra.
