Figure 10: Pure ethane solid I-solid III linear mixing

<b><i>Figure 11.</i></b><i> Linear mixing of ethane solid I and solid III. Spectra at temperatures of 89.7 and 89.8 K in the warming sequence do not fit linear mixing profiles of solid I and III, meaning we cannot completely rule out the likelihood of having witnessed the transitions surrounding solid II.</i><i><br></i><i>Spectra have already been normalized.</i>

***图11*** 乙烷固相I（ethane solid I）与固相III（solid III）的线性混合。升温序列中，89.7 K与89.8 K下采集的光谱并不符合固相I与固相III的线性混合谱型，这意味着我们无法完全排除观测到固相II（solid II）相关相变的可能性。<br>所有光谱均已完成归一化处理。
