Data behind Figure 6.7: Spectral comparison of pre- and post-exsolution of C2H6 +N2 and C2H6–C3H8 +N2 samples

Caption: Examples of nitrogen content pre- and post-exsolution in a C2H6 +N2 (left panel) and 0.95 C2H6 – 0.05 C3H8 +N2 (right panel) sample, as detected in the Raman spectra. While the spectra of the C2H6 +N2 system indicate an absence of nitrogen in the ice formed at 88 K, the C2H6–C3H8 +N2 system retained some amount of nitrogen at 84 K after freezing. This is likely due to the presence of volatile-rich bubbles trapped in the icy matrix.Excel spreadsheet contains four normalized spectra (two C2H6 +N2 and two C2H6–C3H8 +N2) ranging 2300–3000 cm-1.说明：拉曼光谱中检测得到的C₂H₆+N₂（左图）与0.95C₂H₆–0.05C₃H₈+N₂（右图）样品的氮含量出溶前后示例。C₂H₆+N₂体系的光谱表明，88K条件下形成的冰层中未检出氮；而C₂H₆–C₃H₈+N₂体系在84K冷冻后仍留存有一定量的氮。该现象大概率源于冰基质内截留的富含挥发性组分的气泡。本Excel表格包含4条归一化光谱（2条对应C₂H₆+N₂体系、2条对应C₂H₆–C₃H₈+N₂体系），光谱波数范围为2300~3000 cm⁻¹。
