The Basics of UV-Vis Spectroscopy - LMU
thornseshold.cup.uni-muenchen.deelectromagnetic radiation. There are different types of spectroscopy, depending on the wavelength range that is being measured. UV-Vis spectroscopy uses the ultraviolet and visible regions of the electromagnetic spectrum. Infrared spectroscopy uses the lower energy infrared part of the spectrum. 1.2 Wavelength and frequency

The Use of UV-visible Spectroscopy to Measure the Band …
mmrc.caltech.eduSection 2: Limitations of UV-vis spectroscopy The UV-vis measurement is relatively straightforward, and the data obtained is highly reproducible from lab to lab despite differences in lamp sources, spectrometers, experimental configuration, etc. However, to derive a band gap value from a UV-vis measurement, the data must be interpreted.
