First Observation of Defined Structural Motifs in the Sulfur-Iodine Thermochemical Cycle and Their Role in Hydrogen Production

Table 3

The Raman bands recovered by deconvolution of the spectra obtained from samples of the HI-H2O binary system (S1, S2) at 298 K in the spectral region 1000–2500 cm−1. Results in bold were obtained at 514.5 nm, whereas the rest were acquired at 785 nm.
