Definition of absorption spectrum in English: absorption spectrumnoun Physics A spectrum of electromagnetic radiation transmitted through a substance, showing dark lines or bands due to absorption at specific wavelengths. Compare with emission spectrum Example sentencesExamples - The wide absorption spectrum of the electron transfer chain revealed by the transient measurements may contribute to the high efficiency of energy trapping in PSI.
- Following Forster himself, one may use a specific absorption spectrum, a normalized emission spectrum and an estimate of the radiative lifetime.
- The redshift in the absorption spectrum reflects electronic interactions between the porphyrin and the melanins.
- This wavelength also coincides with a peak in the mercury lamp spectrum and with the Soret band of the PpIX absorption spectrum.
- The lowest-energy absorption band lies outside the absorption spectrum of DNA / RNA, allowing selective excitation of 2AP.
