Fig. : Increasing the number of components, the misfit, that is the different between data and sum of components, is reduced. Measured Chemistry: Fe 2+ 3.00(P1.00O4)2•8H2O. Sample Description: Unoriented sample, Instrument settings: Thermo Almega XR 532nm @ 100% of 150mW. We use the processed data, in the range from 2000 to 4000 cm -1 . A spline baseline adjustment is applied. The deconvolution is given in the Figure . Unoriented sample, Instrument settings: Thermo Almega XR 532nm @ 100% of 150mW. We use the raw data, in the range from 2000 to 4000 cm -1 . A spline baseline adjustment is applied. The deconvolution is given in the Figure . Unoriented sample. Instrument settings:Thermo Almega XR 532nm @ 100% of 150mW. We use the raw data, in the range from 2000 to 4000 cm -1 . A spline baseline adjustment is applied.
