UV -Visible spectroscopy Absorption of light in the UV/Visible part of the spectrum (210 ± 900 nm). The transitions that result in the absorption of electromagnetic radiation in this region of the spectrum are transitions between electronic energy levels. Generally, the most probable transition is fromElectronic Transition. Electronic transition refers to the movement of an electron from one energy level to another within an atom or molecule. This process is a fundamental aspect of the interactions between light and matter and plays a crucial role in various fields such as chemistry, physics, and biology.
Ultraviolet and visible radiation interacts with matter which causes electronic transitions (promotion of electrons from the ground state to a high energy state). The ultraviolet region falls in the range between 190-380 nm, the visible region fall between 380-750 nm. The following electronic transitions are possible:The vibrational-electronic spectrum of I 2 in the region from 500-650 nm displays a large number of well-defined bands which, for the most part, correspond to v'<-- 0 transitions connecting the v" = 0 vibrational level of the ground electronic state (denoted as X 1 Σ +) to many different vibrational levels v' of the excited B 3 Π electronic .The possible electronic transitions that light might cause are2: In each possible case, an electron is excited from a full (low energy, ground state) orbital into an empty .

May 18, 2023 — Ultraviolet-Visible spectroscopy makes use of radiation in the Ultraviolet (UV) and Visible (Vis) radiation regions of the electromagnetic spectrum from approximately 200–800 nm (50,000–12,500 cm −1) [].Often the spectroscopic method extends into the near-infrared (NIR) region and is then referred to as UV-Vis-NIR .electronic transitions in uv spectroscopyElectronic transitions between states of different energies give rise to electronic spectra. However, some transitions are more probable, and thus more intense, than others. In UV-vis spectroscopy, for example, the transitions that are "allowed" can give rise to absorption bands that are much more intense than transitions that are "forbidden".Abr 11, 2018 — 6. Interaction of EMR with matter 1.Electronic Energy Levels: At room temperature the molecules are in the lowest energy levels E0.
