DRIFTS (a–d) and Raman spectra (e–h) of Auferstehung (a, b; e, f) and Allerheiligen II (c, d; g, h) along with detailed photos of the measured areas; offset was applied for better comparison. DRIFT spectra originate from the following spots: a) the green area of Fig. 4c (spot 1), b) the green area of Fig. 4c (spot 4); c) the bluish green area of Fig. 5c (spot 3), and d) the orange area of Fig. 5c (spot 1); RSB = reststrahlen band. Raman spectra originate from the following spots: e) the yellow area of Fig. 4c (spot 3), f) the greenish yellow area of Fig. 4c (spot 2); g) the violet area of Fig. 5c (spot 2), and h) the pinkish red area of Fig. 5c (spot 5). × = measured spots
