Fig. 2. (a) XRPD diffractograms of INM at various mole fractions of α- and γ-forms. (b) Intensity of XRPD diffractograms at 2θ = 8.46° (circles) and 2θ = 12.76° (squares) (n = 3). (c) IR spectra of INM at various mole fractions of α- and γ-forms (n = 3). (d) Absorbance of IR spectra at 1649 cm⁻¹ (open triangles), 1680 cm⁻¹ (closed triangles), 1713 cm⁻¹ (closed squares), and 1734 cm⁻¹ (closed circles) (n = 3).
