17 According to the Beer-Lambert law absorbance is proportional to concentration at each wavelength. In principle, one could Choose any wavelength for quantitative esti mations of concentrations. Howe ver, we qe nerally select the wave leng th of maximum absorbance for a gi ven sample and use it in our absorbance measurements. ESO , one should aroid the steep portions of the spectrum- why? Explain.
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.
