resonance absorption

resonance absorption

[′rez·ən·əns əb‚sȯrp·shən]
(nucleonics)
The absorption of neutrons having a narrow range of energies corresponding to a nuclear resonance level of the absorber in a nuclear reactor.
(quantum mechanics)
The absorption of electromagnetic radiation by a quantum-mechanical system at a characteristic frequency satisfying the Bohr frequency condition. Also known as resonance.

The plasmon resonance absorption of AgNPs has a molar extinction coefficient (3 x [10.sup.-11] [M.sup.-1] x [cm.sup.-1]) [15], which allows higher sensitivity in optical detection methods than conventional reagents.
In the film with smoothly changing orientation of the optical axis from parallel to normal to the interface, the resonance absorption takes place for each wavelength with only the position of the resonance shifted.
The essence of the electron spin resonance phenomenon is the resonance absorption of electromagnetic radiation of the unpaired electrons.
Based on the ultra-thin HIS, resonance absorption can be realized when proper electric loss is introduced.
With the formation of gold shell on the surface, the Au-modified SiNWs gained a strong surface plasmon resonance absorption in the near infrared (NIR) region.
