Describe the princibles for atomic spectrocopy, how substances are detected av quantified with the technique
Accepted Answer
Atomic spectroscopy relies on the principle that each element absorbs or emits light at specific wavelengths. When an atom absorbs energy, its electrons transition to higher energy levels. Upon returning to their ground state, they release this energy as photons, producing a characteristic emission spectrum. In absorption spectroscopy, a sample is illuminated with a broad spectrum of light. The amount of light absorbed at specific wavelengths reveals the presence and concentration of elements. Quantitative analysis is achieved by measuring the absorbance or emission intensity, which is directly proportional to the analyte concentration.
