Abstract
In the past few years, scientists are looking for new methods to characterize materials and identify their features in natural media without any separation. The electric field is one of the most important parameters which affects the structure and changes all systems, including electron movement. The electric field affects all processes and transitions in systems that include electric charge. Electron-absorption (Stark) spectroscopy is a method to obtain absorption spectra that are investigated in the presence and absence of an electric field. The electric field makes changes in samples' dipole moment. These changes give much information about how different components approach each other and react, the type of interactions, and how they affect one another. We can predict the occurred processes in the reaction media with this type of information and use them in intermolecular interaction modeling. These spectroscopy methods' most essential usages are in the characterization and identifying the properties of polymers, proteins, nanoparticles, quantum dots, and optical devices' design.
