Application of vibrational spectroscopy in the study of violacein pigment
Váňová, Hana ; Němec, Ivan (advisor) ; Šmejkal, Petr (referee)
This thesis deals with the study of microbial pigment violacein in the real sample of lyophilized microorganisms. The sample was investigated by using methods of vibrational spectroscopy with focusing on the applicability of surface enhanced and resonance micro-Raman spectroscopy. For this purpose several different systems for enhancing Raman intensity together with the set of excitation lasers emitting in the visible light region were used. The conclusion of this thesis are the recommendations connected with the appropriateness of using each amplifying systems and excitation wavelengths for the successful identification of violacein pigment in the sample.

Application of micro-Raman spectroscopy to analysis of artworks
Váňová, Hana ; Němec, Ivan (advisor) ; Šloufová, Ivana (referee)
This thesis deals with the application of micro-Raman spectroscopy to analysis of artworks. The main topic of the thesis was to qualify, select and eventually optimize methods acceptable to identification of indigo dye in the paint layers of artworks. Selected dye was studied in various states using set of excitation lasers emitting in the visible region. There was also studied the real usage of resonance and surface-enhanced methods. The result of the thesis are the conclusions related with the suitability of particular techniques of Raman spectroscopy to identify the target pigment in the art.
