Figure 4
Normalization results of two independently measured data sets by conventional method (a) and MBACK (b). Blue and green lines are the normalized spectra for two independent samples of 5 mM [(CH3)4N]2Zn(SC6H5)4 in DMSO. Red and cyan lines are the normalized spectra for 5 mM [(CH3)4N]2Zn(SC6H5)4 + 200 mM [(CH3)4N]SC6H5 in DMSO. Only with the MBACK normalization is the variation between duplicate samples small in comparison with the chemically relevant spectral changes. |
