WebOct 16, 2024 · Ultraviolet-visible (UV-Vis) spectrophotometry is a technique used to measure light absorbance across the ultraviolet and visible ranges of the electromagnetic spectrum. When incident light strikes matter it can either be absorbed, reflected, or transmitted. The absorbance of radiation in the UV-Vis range causes atomic excitation, which refers ... WebOct 1, 2024 · The principle for UV detection is Beer's law, also called the Beer-Lambert law, where. Absorbance (A) = molar absorptivity (ε) × pathlength ( b) × concentration ( c) Absorbance is defined as the negative logarithm of transmittance, which is the ratio of intensities of transmitted light and the incident light.
WebThis technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
