With the help of the ascertained band parameters, standard and calibration spectra from the infrared measurements in substances, which contain H-O- and C=O-bond groups, the methodology to observe the reactions with infrared spectroscopy as well as the interpretation experienced an essential support.

In this connection, the problems of the keto-enol tautomerism were studied in acetylacetone and (iso-) ascorbic acids.

It furthermore turned out, that the square root values of the integral extinction coefficient of the O=C-stretching vibration modes, which are proportional to the dipole moment changes, varied comparably by the application of neighboring bond groups.

It was able to pursue the phenomenon of the hydration of keto groups with infrared spectroscopy in a simple molecule (butanal).
