NMR spin chromatographic techniques

The first NMR direct and unequivocal identification of four geometric 18:2 conjugated linolenic acid isomers was achieved. The sensitivity and resolution NMR barriers were overcome with selective suppression of the major NMR resonances and reduced 13C spectral width in the 1H–13C HSQC experiment.

 

The method is applicable in the lipid fraction of lyophilized milk and does not require further isolation or derivatization steps; it is selective, sensitive and has very good analytical characteristics.

NMR and DFT Studies of the Catalytic Role of Water

The unique catalytic role of water in aromatic C–H activation at neutral pH was investigated with the use of NMR experiments and DFT calculations of polyphenolic compounds. This approach opens a new vista for the combined use of NMR and DFT studies as tools to understand the molecular basis of the catalytic role of water.

  • Research in Chemical Education
The main objectives of my research in the field of chemical education could be summarized as follows:
  • To engage students in applying chemistry concepts, in developing skills, and in applying them in research practices.
  • To apply major concepts, theoretical principles and experimental findings in chemistry with particular emphasis in spectroscopy.
  • To investigate undergraduate chemistry students’ views and knowledge on some basic aspects and concepts of spectroscopy and use of analogies to aid students in understanding spectroscopic concepts.

[I.P. Gerothanassis, C.G. Kalodimos, J. Chem. Educ. 73, 801-804 (1996)].

Students’ declarative knowledge about basic concepts and features of spectroscopy, such as the physical meaning of ‘wavenumber’in IR spectroscopy and of ‘part per million’in NMR spectroscopy, ‘performing integration, and the ‘resolving power’ of a spectrometer, the results were mostly poor. Interestingly, a clear difference was observed between performance on questions at the high versus the basic level of declarative knowledge.
