Sentences with phrase «electronic transition»

These wavelengths have no physical link to electronic transition levels in pure water.

The light emitted by LEDs is generated by electronic transitions in solid - state semiconductors.

The reason for this is that the term «gamma ray» is used for photons generated from nuclear decay or other nuclear and subnuclear processes, whereas X-rays are generated by electronic transitions involving highly energetic inner electrons.

«Finally, near - infrared spectroscopy provided information on the rest of the full electronic structure by probing electronic transitions into states above the ones probed by the first two techniques.

Many atomic properties have been measured to extraordinary precision: The frequency of an electronic transition in a cesium atom, for example, is used to define the unit of time.

Generally, nuclear transitions are much more energetic than electronic transitions, so gamma - rays are usually more energetic than X-rays.

We then measure band gap energy to within ± 0.01 eV as well as determine whether the electronic transition is direct or indirect with our custom - built photocurrent spectroscopy system.

Methods: When NaCl crystallizes out of water at room temperature with no additional energy added, it emits a cobalt blue glow, indicating that electronic transitions are occurring and in direct contradiction to the general belief that salt crystallization does not involve a change in electronic structure or that the NaCl retains its ionic character.

The adoption of the Electronic Transitions Act of 9 January 2017 in Mozambique has laid down a general legal framework of protection for users of ICT in trade and investment.
