Assignments are suggested for the low-frequency i.r. and Raman bands of the isomorphous series Ph2TeX2(X = Cl, Br, I). Resonance enhancement of the intensity of ν8(TeX) is noted for X = Br, I. The vibrational spectra of R2TeX2(R =p-tolyl, o-tolyl, p-MeOC6H4, C6F5; X = Cl, Br, I) are also reported and assignments of ν(TeX) are suggested. It is concluded that all these compounds have ψ-trigonal bipyramidal
建议分配同构系列Ph 2 TeX 2(X = Cl,Br,I)的低频ir和拉曼频带。的强度的共振增强ν 8(特)指出,为X = Br的,I. R的振动光谱2的TeX 2(R = p -甲苯基,ö甲苯基,p -MeOC 6 ħ 4,C 6 ˚F 5 ; X = Cl,Br,I)也被报告,并且建议ν(TeX)的赋值。结论是所有这些化合物都具有ψ-具有轴卤原子的-三角双锥体结构,与芳基环中取代基的性质无关。在所有情况下ν 8(TeCl)在高于频率被指定ν为(TeCl),但对于溴-和碘代化合物的不对称模式在较高频率发生。
