Infrardeča spektroskopija je uveljavljena analitska metoda z veliko možnostmi uporabe, ki segajo tudi izven področja kemije. Gre za vibracijsko spektroskopijo, s katero na podlagi absorpcije svetlobe določenih valovnih dolžin identificiramo prisotne funkcionalne skupine v molekuli. V sintezni organski kemiji se uporablja v kombinaciji z ostalimi metodami za določanje strukture organskih spojin. Z razumevanjem teoretičnih osnov za absorpcijo infrardeče svetlobe lahko identificiramo vplive na položaj absorpcijskih trakov v spektru neke spojine. V okviru diplomskega dela sem posnela infrardeče spektre izbranih organskih spojin ter v teh spektrih prepoznala karakteristične absorpcije funkcionalnih skupin. Infrared spectroscopy is an established analytical method with a wide range of applications beyond the scope of chemistry. It is categorized as vibrational spectroscopy. Based on absorption of light with specific wavelengths, it is used in organic chemistry to identify functional groups present in a compound. In synthetic organic chemistry, it is used in combination with other methods for structure determination of organic compounds. With insight in theoretical backgrounds of infrared absorption we gain understanding of factors which influence position of absorption bands in the spectra. I have recorded infrared spectra of selected organic compounds and identified in their spectra the characteristic absorption peaks of functional groups. |
