House of Representatives and Senate offices will provide health coverage to Members of Congress and designated congressional staff through the DC Health Exchange SHOP, known as DC Health Link. Members of Congress and designated staff can select coverage through the DC Health Link.
Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei.It determines the physical and chemical properties of atoms or the molecules in which they are contained.owever a frequency scale is commonly used to designate the NMR signals, even though the spectrometer may operate by sweeping the magnetic field, and thus the 42 ppm is 4200 Hz for a 100 MHz reference frequency (rf).
Definition of Near-infrared spectroscopy (NIR). Search the Dictionary. NIR spectroscopy is the measurement of the wavelength and intensity of the absorption of near-infrared light by a sample.Near-infrared light spans the 800 nm - 2.5 Âµm (12,500 - 4000 cm-1) range and is energetic enough to excite overtones and combinations of molecular vibrations to higher energy levels.IR spectroscopy is the measurement of the wavelength and intensity of the absorption of near-infrared light by a sample.
