英文摘要	在24℃和0.1~900MPa压力下测量了含50%水的乙醇溶液和纯乙醇的激光拉曼光谱。研究结果表明,纯乙醇和50%乙醇溶液中的C—H基团振动波数均随压力的增大而增大,它们的各振动峰与压力的关系分别为:纯乙醇:ν1=2881.890+0.00127P+6.213×10-6P2;ν2=2928.707+0.00438P+4.772×10-6P2;ν3=2973.457+0.00889P+3.245×10-6P2;50%乙醇溶液:ν1=2885.616+0.0108P-2.699×10-6P2;ν2=2932.734+0.0137P-3.346×10-6P2;ν3=2978.115+0.0165P-...; Experimental measurement and study of Raman spectra for pure ethanol and 50% ethanol aqueous solution has been conducted at ambient temperature and the pressures of 0.1-900 MPa by using Cubic Zirconia anvil cell. The result shows that the frequency of C-H stretch vibration increases with increasing pressure and each of their relation between the frequency and pressure can be expressed as following: for pure ethanol: v1 = 2881.890 + 0.00127 P + 6.213 x 10(-6) P2; V2 = 2928.707 + 0.004 38 P + 4.772 10(-6) p2; v3 = 2973.457 + 0.0089 P + 3.245 x 10(-6) p2; for 50% ethanol aqueous solution: v1 = 2885.616 + 0.010 8 P-2.699 x 10(-6) P2; v2 = 2932.734 + 0.0137 P - 3.346 x 0(-6) p2; v3 = 2978.115 + 0.0165 P - 4.914 x 10(-6) P2. Furthermore, the authors have observed that at the pressure lower than 550 MPa, the strength of hydrogen bonding becomes stronger with increasing pressure.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000231629300024&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; PubMed; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 2; 08; 1257-1261; 25
