此篇論文是在探討在高壓環境下，用紅外吸收光譜檢測[EMIM][TFSI]和 D-pyridine 之間與[HEMI][TFSI]和 D-pyridine 之間的作用與結構上的變化。首先我們將探討常壓下不同濃度的離子液體與 D-pyridine 的作用，接著以相同環境但加大壓力下去檢測其陰陽離子的變化，發現 D-pyridine 的加入會使陽離子上碳鏈的 C-H以及咪唑鎓 imidazolium 上的 C2-H、C4、5-H 的頻譜產生相對藍位移的現象，再從其頻譜變化中得知，壓力對純離子液體的陰陽離子如何作用，而 D-pyridine 又在何時擠入陰陽離子，或相反的被擠出去，接著，[EMIM][TFSI]和 D-pyridine 之間會傾向與咪唑鎓環上的C2-H 絡合，在[HEMI][TFSI]和 D-pyridine 之間會傾向與咪唑鎓碳鏈上的 O-H 絡合，最後將不同濃度同高壓實驗做成趨勢圖，探討其紅外線吸收峰位置變化，將發現在特定壓力 D-pyridine 會切開離子液體的大團簇，在壓力的上升過程擠進離子液體進而影響陰陽離子，改變其構型，產生新的穩定結構。

In this study, we using infrared (IR) absorption spectroscopy to discover two types of non-covalent interactions for ionic liquids (ILs) and the D-pyridine system at high-pressures. (1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [EMIM] [TSFI], and D-pyridine system or 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [HMIM] [TSFI], and D-pyridine system).

We will discuss about the effects of ionic liquids of different concentrations and D-pyridine under normal pressure, and then continue to detect the changes of anion and cation in the same environment but with increased pressure. It is found that the addition of D-pyridine makes absorption peak of the C-H of the carbon chain on the cation and the C2-H, C4, 5-H on imidazolium produced a relative blue shift, then identify from the changes in the frequency spectrum, how the pressure affects the anions and cations of the pure ionic liquid, and when D-pyridine is squeezed into the anions and cations, or vice versa,

[EMIM][TFSI] and D-pyridine will tend to complex with C2-H on the imidazolium ring, and between [HEMI][TFSI] and D-pyridine will tend to complex with O-H on the imidazolium carbon chain.

Finally, the different concentrations will be compared with the high-pressure experimental trend chart, and the changes in the infrared absorption peak position will be discussed. It will be found that D-pyridine will cleave the ionic liquid under a certain pressure. The large clusters squeezed into the boots of the ionic liquid in the process of rising pressure affect the anions and cations, change their configuration, and produce a new stable structure.
