Atomic absorption spectrophotometry is a method for the quantitative determination of metal ions. a) Describe in detail the AAS instrument and especially the parts that differ from a normal spectrophotometer. b) What light source is used in this technology and how does it work? c) What interferences can occur with this equipment? d) What is the theoretical basis of the AAS method?
Electronic Transitions and Spectroscopy
The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.
Photoelectron Spectroscopy
Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
