Chapter 1: UV-Visible & Fluorescence Spectroscopy

(often abbreviated as UV-Vis) and fluorescence emission spectroscopy. These two methods are measured over the same range of wavelengths, but are caused by two different phenomena. In both cases, the wavelengths used are the near-ultraviolet range (200 to 400 nm) and the visible range (400 to 750 nm).

Chapter 1: NMR Coupling Constants 2 Figure 1-2: The NMR spectrum of 1,1-dichloroethane, collected in a 60 MHz instrument. For both A and B protons, the peaks are spaced by 0.1 ppm, equal to 6 Hz in this instrument. This time, the peak spacing is 0.1 ppm. This is equal to a J constant of (0.1 ppm • 60 MHz) = 6 Hz, the same as before.

Visible absorption spectroscopy is often combined with UV absorption spectroscopy in UV/Vis spectroscopy. Although this form may be uncommon as the human eye is a similar indicator, it still proves useful when distinguishing colours.
