Abstract

In this work, assignment of C-O stretching bands in dinuclear metal carbonyls of the type $[M(CO)_4X]_2$, (M= Mn, Tc, Re; X= Cl, Br, I) was made by using the Cotton-Kraihanzel approximation. In the application of the mentioned approximation it was shown that uncertainty in the measurement of frequencies must be considered in the calculations. For this reason, the relations of standard deviation were derived. Band assignment for the molecules under study were found to be ${vb_{3u}}^{(1)}>vb_{1u}>{vb_{3u}}^{(2)}>vb_{2u}$.

Özet

Bu çalışmada Cotton-Kraihanzel yaklaşımı kullanılarak $D_{2h}$ simetri nokta grubundaki $[M(CO)_4X]_2$, (M=Mn, Tc, Re; X=Cl, Br, I) tipi iki çekirdekli metal karbonillerin C-O gerilme bantlarının simetri etiketlemesi yapılmıştır. Cotton-Kraihanzel yaklaşımının uygulanmasında frekans ölçümlerindeki belirsizliğin hesaplamalara yansımasının göz önüne alınması gerektiği ortaya konulmuş ve bu amaçla gerekli standart sapma bağıntıları türetilmiştir. İncelenen moleküller için simetri etiketlemesi ${vb_{3u}}^{(1)}>vb_{1u}>{vb_{3u}}^{(2)}>vb_{2u}$, şeklinde bulunmuştur.
