Application of spectrophotometers
 Klimešová, Marie ; Čmiel, Vratislav (referee) ; Kolář, Radim (advisor)
The work deals with the important analytical method - spectrometry. It is based on measurement of absorption of radiation in a wavelength range. On this principle can determine the absorbance and transmittance of the measured samples. The thesis also describes events related to the excitation of molecules. These include absorption, vibrational relaxation, internal conversion, inter-system crossing, fluorescence, phosphorescence and delayed fluorescence. The practical part includes three experimental measurements. The first measurement is the concentrations of potassium permanganate solution. In a second experiment, verifying the validity of Lambert-Beer law. In the third experiment, the fluorescence measurement of fluorescein and detection of fluorophore concentration dependence on fluorescence intensity. Measurement is performed in an environment SpectraSuite with the use of school spectrometers USB2000 + and USB650 Red Tide.
