The nature, role, and significance of low intensity spectral bands con?tained
within the infrared spectra of kernels of high-yielding maize hybrids: ZP
341, ZP 434, and ZP 505 were observed in this study. The observations were
performed to identify or?ganic molecules and their structural properties.
The occurrence of unstable state of organic compounds and their functional
groups are conditioned by such a process. The set hypoth?esis holds that
there is a necessity to study the existence of many and low intensity
spectral bands, not observed so far, occurring in different patterns (low
intensity bands, single or grouped). They should be observed and the
dynamics of their formation, caused by their different movements, including
the possibility of their cancellation or amplification, should be explained.
Such spectral bands most often appear in the wave number range of 400-950
cm-1. They occur in several wave numbers up to 3,000 cm-1 and are caused by
different types of vibration movements (valence and deformation vibrations)
of organic compounds and their functional groups: primary, secondary, and
tertiary amides, proteins, free amino acids, alkanes, alkenes, aldehydes,
ketones, aromatic compounds, cellulose, carbohydrates, car?boxylic acids,
ethers, and alcohols. An unbiased analysis of low intensity spectral bands
of maize hybrid kernels reveals that their occurrence is similar. Small
differences, for some cases of the occurrence of low intensity spectral
bands, can barely be ascertained. In this way, it is possible to establish
not only the chemical composition of organic compounds of kernels of
observed maize hybrids, but also it is possible to indicate their unstable,
confor?mational, and functional properties.
