  2. Doppler broadening - Wikipedia

    en.wikipedia.org/wiki/Doppler_broadening

    A particular case is the thermal Doppler broadening due to the thermal motion of the particles. Then, the broadening depends only on the frequency of the spectral line, the mass of the emitting particles, and their temperature , and therefore can be used for inferring the temperature of an emitting (or absorbing) body being spectroscopically ...

  4. Electrophoretic light scattering - Wikipedia

    en.wikipedia.org/wiki/Electrophoretic_light...

    Electrophoretic light scattering (also known as laser Doppler electrophoresis and phase analysis light scattering) is based on dynamic light scattering. The frequency shift or phase shift of an incident laser beam depends on the dispersed particles mobility.

    Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?

  6. Spectral method - Wikipedia

    en.wikipedia.org/wiki/Spectral_method

    For very small problems, the spectral method is unique in that solutions may be written out symbolically, yielding a practical alternative to series solutions for differential equations. Spectral methods can be computationally less expensive and easier to implement than finite element methods; they shine best when high accuracy is sought in ...

  8. Doppler spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Doppler_spectroscopy

    Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star. As of November 2022, about 19.5% of known extrasolar planets ...
