Ammonium stearate treated magnesium

Figure 3.20 Infrared absorption peak area ratio (C-H stretch [from AS] (A(c h)s)/C) H stretch [from Mg(OH)2] ( o-h)s) obtained from DRIFTS spectra of ammonium stearate treated magnesium hydroxide.

The second example shows how DRIFTS can give insight into the environment in which adsorbed species reside and how this environment changes with addition level [46]. Figure 3.19 shows the carbonyl region of substrate subtracted DRIFTS spectra of magnesium hydroxide that has been treated with varying levels of stearate (from ammonium stearate).
