Infrared spectroscopy is one of the most commonly used spectroscopic
methods in criminalistics, through which various kinds of criminalistic
traces can be explored. It finds wide application in academic research,
but also in research of forensic laboratories in order to obtain results ap-
plicable in criminalistic practice. The paper provides information about
selected possibilities of using Fourier transform infrared spectroscopy
and its modifications in investigation of specific criminalistic traces such
as documents, banknotes, cosmetics, blood traces and adhesive materials
