Spectroscopy in a sentence

Although absorption spectroscopy and emission spectroscopy are different in principle, they are closely related in practice; any technique for emission spectroscopy can also be used for absorption spectroscopy.

Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) involve visible and ultraviolet light.

Atoms Atomic spectroscopy was the first application of spectroscopy developed.

More convincing are the correlations between electronegativity and chemical shifts in NMR spectroscopy citation or isomer shifts in Mössbauer spectroscopy citation (see figure).

Rotations are collective motions of the atomic nuclei and typically lead to spectra in the microwave and millimeter-wave spectral regions; rotational spectroscopy and microwave spectroscopy are synonymous.

Simple accounts often suggest that experimental molecular orbital energies can be obtained by the methods of ultra-violet photoelectron spectroscopy for valence orbitals and X-ray photoelectron spectroscopy for core orbitals.

Instead of solely using light in the visible spectrum, the new method also used spectroscopy in the infrared spectrum, which is not visible to the human eye.

On basis of application, the process spectroscopy market across the globe is sectored into food & agriculture, polymer, pulp & paper, pharmaceuticals, water & wastewater, oil & gas, chemical, and metal & mining segments.

Only after using spectroscopy did they come to the conclusion that it was the aftermath of a black hole flying through a halo of gas surrounding the host galaxy.

Raman spectroscopy provides important insights into the chemical makeup of a sample by using light to excite molecular vibration.

To confirm the chitin identity, Matthews used different techniques such as circular dichroism and Fourier-transform infrared spectroscopy — a process to definitively identify compounds — to match the molecular fingerprint to commercial chitin from shrimp.

He added that the devices use a technology called Raman spectroscopy, which works fine in limited, often lab-controlled circumstances in which a sample only has one or two substances present.

In the meantime, the team is preparing for further observations and spectroscopy with Webb.

Jia Zhang et al, Ultrafast terahertz Stark spectroscopy reveals the excited-state dipole moments of retinal in bacteriorhodopsin, Proceedings of the National Academy of SciencesDOI: 10.1073/pnas.

Neutron spectroscopy measurements were performed at ILL Instruments IN5 (TOF spectrometer) and IN11 (neutron spin-echo spectrometer).

To utilize UV frequency combs containing a million closely spaced spectral lines for spectroscopy applications, the researchers needed a method capable of achieving high spectral resolution—beyond the capabilities of existing spectrometers.

Using solution NMR spectroscopy, scientists from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) were able to examine each of its 600 unstructured individually and by doing so discovered a new interaction network.

Lange's research group further developed nuclear magnetic resonance spectroscopy (NMR) especially for this task under an ERC Grant; cryo-EM expert Professor Gunnar Schröder from Forschungszentrum Jülich performed the electron-microscopic investigations.
