When analyzing for titanium (Ti) using ICP-OES, I find the 323.452 nm emission band of Ti that I planned to measure is very close in wavelength to an argon (Ar) emission line at 324.369 What type of interference would this be? Is this likely to be a problem in this analysis? Why or why not? How would this interference impact the emission intensity data I collect?
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.
