Infrared spectrum

Infrared radiation was discovered in 1800 by astronomer Sir William Herschel, who discovered a type of invisible radiation in the spectrum lower in energy than red light, by means of its effect on a thermometer.[6] Slightly more than half of the total energy from the Sun was eventually found to arrive on Earth in the form of infrared. The balance between absorbed and emitted infrared radiation has a critical effect on Earth's climate.

  3. This technique covers the region of the electromagnetic spectrum between the visible (wavelength of 800 nanometres) and the short-wavelength microwave (0.3 millimetre). The spectra observed in this region are primarily associated with the internal vibrational motion of molecules, but a few light molecules will have rotational transitions lying in the region. For the infrared region, the wave number (ν̄, the reciprocal of the wavelength) is commonly used to measure energy. Infrared spectroscopy historically has been divided into three regions, the near infrared (4,000–12,500 inverse centimetres [cm−1]), the mid-infrared (400–4,000 cm−1) and the far infrared (10–400 cm−1). With the development of Fourier-transform spectrometers, this distinction of areas has blurred and the more sophisticated instruments can cover from 10 to 25,000 cm−1 by an interchange of source, beam splitter, detector, and sample cell.

Infrared light from the Sun accounts for 49%[22] of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths. Visible light or ultraviolet-emitting lasers can char paper and incandescently hot objects emit visible radiation. Objects at room temperature will emit radiation concentrated mostly in the 8 to 25 μm band, but this is not distinct from the emission of visible light by incandescent objects and ultraviolet by even hotter objects (see black body and Wien's displacement law).[23]

Raman spectroscopy is based on the absorption of photons of a specific frequency followed by scattering at a higher or lower frequency. The modification of the scattered photons results from the incident photons either gaining energy from or losing energy to the vibrational and rotational motion of the molecule. Quantitatively, a sample (solid, liquid, or gas) is irradiated with a source frequency ν0 and the scattered radiation will be of frequency ν0 ± νi, where νi is the frequency corresponding to a vibrational or rotational transition in the molecule. Since molecules exist in a number of different rotational and vibrational states (depending on the temperature), many different values of νi are possible. Consequently, the Raman spectra will consist of a large number of scattered lines. IR spectra of solids and liquids are usually obtained by dissolving the sample in a relatively IR The Infrared spectra of thousands of compounds have been determined and compiled by several..

Definition of infrared spectrum in the Definitions.net dictionary. Information and translations of infrared spectrum in the most comprehensive dictionary definitions resource on the web In infrared photography, infrared filters are used to capture the near-infrared spectrum. Digital cameras often use infrared blockers. Cheaper digital cameras and camera phones have less effective filters and can "see" intense near-infrared, appearing as a bright purple-white color. This is especially pronounced when taking pictures of subjects near IR-bright areas (such as near a lamp), where the resulting infrared interference can wash out the image. There is also a technique called 'T-ray' imaging, which is imaging using far-infrared or terahertz radiation. Lack of bright sources can make terahertz photography more challenging than most other infrared imaging techniques. Recently T-ray imaging has been of considerable interest due to a number of new developments such as terahertz time-domain spectroscopy. The observation of the vibrational Raman spectrum of a molecule depends on a change in the molecules polarizability (ability to be distorted by an electric field) rather than its dipole moment during the vibration of the atoms. As a result, infrared and Raman spectra provide complementary information, and between the two techniques all vibrational transitions can be observed. This combination of techniques is essential for the measurement of all the vibrational frequencies of molecules of high symmetry that do not have permanent dipole moments. Analogously, there will be a rotational Raman spectra for molecules with no permanent dipole moment that consequently have no pure rotational spectra. The absorption spectra of these superior fluorescent dyes cover the entire spectrum and match the principal output wavelengths of common excitation sources IR spectrum. Infrared Radiation The vibrational frequency of a bond is measured in this spectroscopic method. Infrared Spectra are recorded using an ATR detector. What does ATR stand for

Infrared Spectroscopy (FT-IR) Infrared spectroscopy is a technique used to identify various functional groups in unknown substances through the identification of different covalent bonds that are present.. In the semiconductor industry, infrared light can be used to characterize materials such as thin films and periodic trench structures. By measuring the reflectance of light from the surface of a semiconductor wafer, the index of refraction (n) and the extinction Coefficient (k) can be determined via the Forouhi-Bloomer dispersion equations. The reflectance from the infrared light can also be used to determine the critical dimension, depth, and sidewall angle of high aspect ratio trench structures.

The IR Spectrum Table is a chart for use during infrared spectroscopy. The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups Infrared radiation can be used as a deliberate heating source. For example, it is used in infrared saunas to heat the occupants. It may also be used in other heating applications, such as to remove ice from the wings of aircraft (de-icing).[29] Infrared can be used in cooking and heating food as it predominantly heats the opaque, absorbent objects, rather than the air around them.

Infrared light is also useful for observing the cores of active galaxies, which are often cloaked in gas and dust. Distant galaxies with a high redshift will have the peak portion of their spectrum shifted toward longer wavelengths, so they are more readily observed in the infrared.[8]

Infrared spectra have been measured for over a century (8). In this time, perhaps millions of samples have been analyzed, giving us a vast database of peak positions for known functional groups Most incident photons are scattered by the sample with no change in frequency in a process known as Rayleigh scattering. To enhance the observation of the radiation at ν0 ± νi, the scattered radiation is observed perpendicular to the incident beam. To provide high-intensity incident radiation and to enable the observation of lines where νi is small (as when due to rotational changes), the source in a Raman spectrometer is a monochromatic visible laser. The scattered radiation can then be analyzed by use of a scanning optical monochromator with a phototube as a detector.
