An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups. [1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify ...
Infrared spectroscopy ( IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or ...
SWIR, IR-B DIN: 1.4–3 μm 100–214 THz 413–886 meV 2,070–966 K (1,797–693 °C) Water absorption increases significantly at 1,450 nm. The 1,530 to 1,560 nm range is the dominant spectral region for long-distance telecommunications (see transmission windows). Mid-wavelength infrared MWIR, IR-C DIN; MidIR. [20]
Infrared window. As the main part of the 'window' spectrum, a clear electromagnetic spectral transmission 'window' can be seen between 8 and 14 μm. A fragmented part of the 'window' spectrum (one might say a louvred part of the 'window') can also be seen in the visible to mid-wavelength infrared between 0.2 and 5.5 μm.
Far infrared ( FIR) or long wave refers to a specific range within the infrared spectrum of electromagnetic radiation. It encompasses radiation with wavelengths ranging from 15 μm ( micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz. This places far infrared radiation within the CIE IR-B and IR-C ...
Cyclooctadiene iridium chloride dimer is an organoiridium compound with the formula [Ir (μ 2 -Cl) (COD)] 2, where COD is the diene 1,5-cyclooctadiene (C 8 H 12 ). It is an orange-red solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in homogeneous catalysis. [1]
Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. [10] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...
