Activities of the Laboratory of Molecular Spectroscopy cover a wide range of themes in the field of application of infrared spectroscopy in physical and analytical chemistry. Laboratory is equipped by the room for simpler organic syntheses, and infrared spectrometer. Accessories allow spectral measurements of liquid and solid samples.

The main research themes in the field of physical chemistry include:

  • intermolecular interactions in condensed phase, mainly structure and dynamics of liquid mixtures;
  • thermicaly induced structural changes in solid phase;
  • vibrational characterisation of ligands and complex compounds;
  • vibrational spectroscopy of substituted acetylenes.

In the last few years a considerable interest of the Laboratory was concerned to application of infrared spectroscopy in analysis of complex samples, such as biological systems, food products and materials. In the framework of these investigations, new advanced chemometric methods of the spectroscopic data analysis were developed, which opens very wide capabilities for their further application. The problems on which these methods were developed are:

  • identification and analysis of traditional Croatian food products, mainly honey and cheese;
  • characterisation and identification of pollen;
  • diagnostics of honeybee diseases;
  • characterisation, analysis and correlation of macroscopic properties of materials with infrared spectra.

Characterization and identification of pollen by vibrational spectroscopy and chemometrics

Characterization and identification of pollen by vibrational spectroscopy and chemometrics

Principal Investigator: Boris Zimmermann

Vibrational (infrared and Raman) spectroscopy of pollen shows great potential for systematic collection of data on ecosystem and plant-environment interactions. The study demonstrates rapid and economical spactroscopic measurement of biochemical composition of pollen grains that provides efficient phenotyping of seed plants. Pollen content can significantly vary between closely related plant genera and species, and can even mirror the seasonal adaptation of the parent plant.
