摘　　要：通过变温红外和变温激光拉曼光谱研究了一个新的席夫碱型液晶化合物．结果表明，该化合物的羰基和亚胺基团在红外光谱中对ＳＢ－ＳＧ转变较敏感；在拉曼光谱中，对Ｎ＊－ＳＢ较敏感．A new Schiff base liquid crystal was studied by using variable-temperature FTIR spectra and laser Raman spectra. The iR studies show that carbonyl and imino groups are sensitive to the SB-→SG transition, the Raman results show that the carbonyl group and imino groups are sensitive to the change of N*→SB.
