This paper discusses the application of the infrared (IR) spectroscopy method for determination of structural properties of maize hybrid grains. The IR spectrum of maize grain has been registered in the following hybrids: ZP 341, ZP 434 and ZP 505. The existence of spectral bands varying in both number and intensity, as well as their shape, frequency and kinetics have been determined. They have been determined by valence oscillations and deformation oscillations of the following organic compounds: alkanes, alkenes, alkynes, amides, alcohols, ethers, carboxylic acids, esters and aldehydes and ketones, characteristic for biogenic compounds such as carbohydrates, proteins and lipids. In this way, possible changes in the grain structure of observed maize hybrids could be detected.
U ovom radu razmatra se primena metode infracrvene spektro skopije na zrnu hibrida kukuruza radi utvrđivanja njegovih mogućih strukturnih karakteristika. Izvršeno je registrovanje infracrvenog spektra zrna hibrida kukuruza: ZP 341, ZP 434 i ZP 505. Pokazano je postojanje različitih spek tralnih traka, kako po broju i intenzitetu, tako i po njihovom obliku, frekvenciji i kinetici. Do njih se dolazi valentnim oscilacijama i deformacijama funkcionalnih grupa: alkana, alkena, alkina, amida, alkohola, etra, karboksilne ki seline, estra, aldehida i ketona, koje su karakteristične za biogena jedinjenja ugljovodonika, proteina i lipida. Na ovaj način se dolazi do mogućih razlika u strukturi zrna ispitivanih hibrida kukuruza.
