  2. Transition metal complexes of 1,10-phenanthroline - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_complexes...

    1,10-Phenanthroline is an inhibitor of metallopeptidases, with one of the first observed instances reported in carboxypeptidase A. [11] Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme . 1,10-Phenanthroline targets mainly zinc metallopeptidases, with a much ...

  3. 1,10-Phenanthroline - Wikipedia

    en.wikipedia.org/wiki/1,10-Phenanthroline

    1,10-Phenanthroline (phen) is a heterocyclic organic compound. It is a white solid that is soluble in organic solvents. The 1,10 refer to the location of the nitrogen atoms that replace CH's in the hydrocarbon called phenanthrene. Abbreviated "phen", it is used as a ligand in coordination chemistry, forming strong complexes with most metal ions.

  4. Spectrochemical series - Wikipedia

    en.wikipedia.org/wiki/Spectrochemical_series

    A spectrochemical series is a list of ligands ordered by ligand "strength", and a list of metal ions based on oxidation number, group and element.For a metal ion, the ligands modify the difference in energy Δ between the d orbitals, called the ligand-field splitting parameter in ligand field theory, or the crystal-field splitting parameter in crystal field theory.

  6. Spectral line - Wikipedia

    en.wikipedia.org/wiki/Spectral_line

    This is the spectrum of a blue sky somewhat close to the horizon, looking east with the sun to the west at around 3–4 pm on a clear day. A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. It may result from emission or absorption of light in a narrow frequency range, compared with the nearby ...

    Energy level diagram showing relationship between Rayleigh, Raman, and resonance Raman scattering and fluorescence. Resonance Raman spectroscopy (RR spectroscopy or RRS) is a variant of Raman spectroscopy in which the incident photon energy is close in energy to an electronic transition of a compound or material under examination.

  8. Phasor approach to fluorescence lifetime and spectral imaging

    en.wikipedia.org/wiki/Phasor_approach_to...

    In Fluorescence lifetime and spectral imaging, phasor can be used to visualize the spectra and decay curves. [1] [2] In this method the Fourier transformation of the spectrum or decay curve is calculated and the resulted complex number is plotted on a 2D plot where the X-axis represents the real component and the Y-axis represents the imaginary ...

  9. Atomic spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_spectroscopy

    In physics, atomic spectroscopy is the study of the electromagnetic radiation absorbed and emitted by atoms. Since unique elements have unique emission spectra , atomic spectroscopy is applied for determination of elemental compositions.
