  • X-ray spectroscopy
    X-ray spectroscopy is a gathering name for several spectroscopic techniques for characterization of materials by using x-ray excitation.
  • Electron paramagnetic resonance
    Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials with unpaired electrons.
  • Nuclear magnetic resonance spectroscopy
    Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei.
  • Spectral density
    The power spectrum of a time series describes the distribution of power into frequency components composing that signal.
  • Phosphorescence
    Phosphorescence is a specific type of photoluminescence related to fluorescence.
  • Colorimetry (chemical method)
    In physical and analytical chemistry, colorimetry or colourimetry is a technique "used to determine the concentration of colored compounds in solution.
  • Spectrum analyzer
    A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument.
  • Hyperfine structure
    In atomic physics, hyperfine structure is the different effects leading to small shifts and splittings in the energy levels of atoms, molecules and ions.
  • The Unscrambler
    The Unscrambler® X is a commercial software product for multivariate data analysis, used for calibration of multivariate data which is often in the application of analytical data such as near infrared spectroscopy and Raman spectroscopy, and development of predictive models for use in real-time spectroscopic analysis of materials.
  • Singlet oxygen
    Singlet oxygen is a high energy form of oxygen.
  • Ultraviolet–visible spectroscopy
    Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region.
  • Stokes shift
    Stokes shift is the difference (in wavelength or frequency units) between positions of the band maxima of the absorption and emission spectra (fluorescence and Raman being two examples) of the same electronic transition.
  • Quantum efficiency
    The term quantum efficiency (QE) may apply to incident photon to converted electron (IPCE) ratio, of a photosensitive device or it may refer to the TMR effect of a Magnetic Tunnel Junction.
  • Spectrometer
    In physics, a spectrometer is an apparatus to measure a spectrum.
  • Raman scattering
    Raman scattering or the Raman effect /ˈrɑːmən/ is the inelastic scattering of a photon upon interaction with matter.
  • Single-molecule experiment
    A single-molecule experiment is an experiment that investigates the properties of individual molecules.
  • Fluorescence correlation spectroscopy
    Fluorescence correlation spectroscopy (FCS) is a correlation analysis of fluctuation of the fluorescence intensity.
  • Frequency comb
    A frequency comb is a spectrum consisting of a series of discrete, equally spaced elements.
  • Spectral line shape
    Spectral line shape describes the form of a feature, observed in spectroscopy, corresponding to an energy change in an atom, molecule or ion.
  • Opacity (optics)
    Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light.
  • Spectral hole burning
    Spectral hole burning is the frequency selective bleaching of the absorption spectrum of a material, which leads to an increased transmission (a "spectral hole") at the selected frequency.
  • Hund's rules
    In atomic physics, Hund's rules refers to a set of rules that German physicist Friedrich Hund formulated around 1927, which are used to determine the term symbol that corresponds to the ground state of a multi-electron atom.
  • Electromagnetic absorption by water
    The absorption of electromagnetic radiation by water depends on the state of the water.

    The Federation of Analytical Chemistry and Spectroscopy Societies or FACSS is a scientific society incorporated on June 28, 1972 with the goal of promoting research and education in analytical chemistry.
  • Spectrum
    A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary infinitely within a continuum.
  • Hund's cases
    In rotational-vibrational and electronic spectroscopy of diatomic molecules, Hund's coupling cases are idealized cases where specific terms appearing in the molecular Hamiltonian and involving couplings between angular momenta are assumed to dominate over all other terms.
