 ATR-FTIR Spectroscopy)
In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and simultaneous increase in frequency and energy, is known as a negative redshift, or … Zobraziť viac The history of the subject began with the development in the 19th century of classical wave mechanics and the exploration of phenomena associated with the Doppler effect. The effect is named after Zobraziť viac In general relativity one can derive several important special-case formulae for redshift in certain special spacetime geometries, as summarized in the following table. In all cases the magnitude of the shift (the value of z) is independent of the wavelength. Zobraziť viac The interactions and phenomena summarized in the subjects of radiative transfer and physical optics can result in shifts in the wavelength and frequency of electromagnetic … Zobraziť viac • Cosmic crystallography • Gravitational potential • Relativistic Doppler effect Zobraziť viac The spectrum of light that comes from a source (see idealized spectrum illustration top-right) can be measured. To determine the redshift, one … Zobraziť viac The redshift observed in astronomy can be measured because the emission and absorption spectra for atoms are distinctive and well known, … Zobraziť viac The opposite of a redshift is a blueshift. A blueshift is any decrease in wavelength (increase in energy), with a corresponding increase in frequency, of an electromagnetic wave Zobraziť viac WebSo, what is FTIR? The Fourier Transform converts the detector output to an interpretable spectrum. The FTIR generates spectra with patterns that provide structural insights. …
