Abstract (2. Language): 
In this study, characterization of monochlorophenols (o-, m-, p-chlorophenol) has been observed by using FTIR spectroscopy as well as the effects of molecule symmetry on vibrational frequencies of molecule. Vibrational modes of monochlorophenols investigated by means of ATR which is the best choice for liquid phase. The observed infrared bands of monochlorophenols are assigned with their ge¬ometrical structures. Isomers with their same chemical formula and molecular weights would be a cri¬tical choice to express ideas about symmetry effects on characteristic wavenumbers of molecules. It is concluded that symmetry of molecules affects the wavenumber of functional group in the molecule.

Abstract (Original Language): 
Bu çalışmada, (o-, m-, p-klorofenol) monoklorfenollerin karakterizasyonu FTIR spektroskopisi kullanılarak elde edilmiş, buna ek olarak molekül simetrisinin moleküle ait titreşim frekansları üzerine etkisi gözlenmiştir. Monoklorfenollerin titreşim modları incelenirken sıvılar için en iyi seçim olan ATR seçilmiştir. monoklorfenollerden elde edilen kırmızı-altı bandlar, monoklorfenollerin geometrik yapıları göz önüne alınarak atıfları yapılmıştır. Molekülün simetrisinin özgün dalga sayılarının üzeri¬ne etkisini açıklayabilmek adına seçim yapılırken tamamıyla molekül formülleri ve molekül ağırlıkla¬rı aynı olan izomerler seçilmiştir. Molekülün simetrisinin, fonksiyonel grupların özgün dalga sayıları¬na etki ettiği sonucuna varılmıştır.
