    Tide is a tool to identify peptides from tandem mass spectra. It is an independent re-implementation of the SEQUEST algorithm, which identifies peptides by comparing the observed spectra to a catalog of theoretical spectra derived in silico from a database of known proteins.

    en.wikipedia.org/wiki/Optical_spectrometer

    In the mid- to far-IR, spectra are typically expressed in units of Watts per unit wavelength (μm) or wavenumber (cm −1). In many cases, the spectrum is displayed with the units left implied (such as "digital counts" per spectral channel). A comparison of the four abscissa types typically used for visible spectrometers.

    An apples-to-apples comparison of these two MLPs shows that one is a better value right now.

  5. Time-resolved spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Time-resolved_spectroscopy

    In physics and physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques.Most often, processes are studied after the illumination of a material occurs, but in principle, the technique can be applied to any process that leads to a change in properties of a material.

  6. Photoluminescence excitation - Wikipedia

    en.wikipedia.org/wiki/Photoluminescence_excitation

    Photoluminescence excitation (abbreviated PLE) is a specific type of photoluminescence and concerns the interaction between electromagnetic radiation and matter.It is used in spectroscopic measurements where the frequency of the excitation light is varied, and the luminescence is monitored at the typical emission frequency of the material being studied.

  7. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...

    en.wikipedia.org/wiki/Braided_fishing_line

    Braids were originally made from natural fibers such as cotton and linen, but natural fiber braids (with the very rare exception of braided silk) have long since been replaced by braided or woven fibers of synthetic materials like Dacron, Spectra or micro-dyneema into a strand of line. For these strands another term is used i.e. "carrier" as ...

  9. Vibrational circular dichroism - Wikipedia

    en.wikipedia.org/wiki/Vibrational_circular_dichroism

    Vibrational circular dichroism (VCD) is a spectroscopic technique which detects differences in attenuation of left and right circularly polarized light passing through a sample.
