The vibrational spectrum of monomeric ReF3O2 isolated in inert-gas matrices has been studied using i.r. and Raman techniques. From a total of six possible structural models based on trigonal-bipyramidal or square-pyramidal geometries, only one structure [a trigonal bipyramid with equatorial oxygen atoms (C2v symmetry)] satisfies the observed spectra in terms of selection rules and relative band intensities
已使用ir和Raman技术研究了在惰性气体基质中分离出的单体ReF 3 O 2的振动光谱。在基于三角-双锥体或正方形-锥体几何结构的总共六个可能的结构模型中,只有一个结构[具有赤道氧原子(C 2 v对称性)的三角双锥体]在选择规则和相对谱带强度方面满足观察到的光谱。ReF 3 O 2的新合成已用于同位素富集的18 O材料的预加速器中,其光谱证实ReF 3 O 2包含两个等效的氧原子。这个C因此, 2 v结构类似于针对ClF 3 O 2提出的结构。还详细讨论了在这些研究过程中作为副产物产生的ReFO 3的振动光谱。
