A non-bonding orbital is a lone pair on, say, oxygen, nitrogen or a halogen. Beer-Lambert example The Beer-Lambert-Bouguer law, generally called the Beer-. While interaction with infrared light causes molecules to undergo vibrational transitions, the shorter wavelength, higher energy radiation in the UV (200-400 nm) and visible (400-700 nm) range of the electromagnetic spectrum causes many organic molecules to undergo electronic transitions. The region from 500 to 300 nm provides valuable information. It was apparent that the absorbance spectra of the pelleted debris remained fairly linear over the wavelengths used by Beer and Eshel (),. 1. The units of concentration are g/L, thus e will have dimensions of g -1 L cm -1. Figure 6 shows the absorbance spectrum in the visible region for a complex metal ion.
