Comparison of the Raman spectra of Gly·MgSO4·5H2O, measured by us using a B&W Tek i-Raman Plus spectrometer (532 nm laser at 18 mW power, 3 cm−1 resolution) and by Tepavitcharova et al. (2012) using a Nicolet 6700 FT–IR with an FT Raman module (1064 nm laser at ∼300 mW power, 2 cm−1 resolution). Intensity differences at high frequencies may be due to the difference in excitation wavelength between the two observations. See Table 10 for band centres and mode assignments obtained from both data sets. |
