Review of Scientific Instruments, 1950
This paper is a review of the various types of beta-ray spectrographs and spectrometers. The principal theoretical results as to the resolving power and luminosity attainable under various conditions are briefly related. Finally the construction and performance data of a number of instruments described in the literature are collected, and compared by ...

Spectroscopic electron tomography
Ultramicroscopy, 2003The elemental mapping techniques in analytical transmission electron microscopy (TEM), energy filtered imaging (EFTEM) and EDX-mapping, are shown to provide new routes for tomographic reconstructions of 3D chemical maps on the nanoscale. The inelastic scattering does not only provide chemical sensitivity but also improves the linear projection ...

Spectroscopic Studies of Sulfides
Reviews in Mineralogy and Geochemistry, 2006Spectroscopic methods are the most direct and powerful means of obtaining experimental information on the electronic structures of materials. They also provide crucial information on aspects of crystal structure, crystal chemistry, solution chemistry and chemical speciation in mineralogical or geochemical systems.

Multiplexed Spectroscopic Detections
Annual Review of Analytical Chemistry, 2008This review describes various platforms used for multiplexed spectroscopic analysis. We highlight the use of different types of spectroscopy for multiplexed detections, including Raman spectroscopy, surface-enhanced Raman spectroscopy, surface plasmon resonance, and fluorescence.

Spectroscopic order out of spectroscopic chaos
International Journal of Quantum Chemistry, 1987AbstractA concept is advanced explaining how low resolution studies of chaotic spectral regions can result in assignable regular spectra. The concept draws on ideas from resonance scattering theory, and application is made to interpretation of vibrational spectra in the quasicontinuum.

Some Spectroscopic Reminiscences
Annual Review of Physical Chemistry, 1995We review a number of essentially spectroscopic problems in this personal account. The structure of high-temperature species remains a topic of considerable broad interest. The binary fluorides of essentially every element are stable as the isolated gas-phase molecular species. As such they provide a means of comparing bonding with the entire periodic

THE INTERFEROMETER AND THE SPECTROSCOPE: MICHELSON'S STANDARDS AND THE SPECTROSCOPIC COMMUNITY
Nuncius, 2003SUMMARY This is a study of the role of the spectroscope in the making of the interferometer. As Michelson developed interferential refractometry into a multifaceted field of research, he drew on the spectroscope as a complementary instrument, but also highlighted the increased accuracy that interferometry promised.

Electron Spectroscopic Imaging
Ultrastructural Pathology, 1987Electron spectroscopic imaging (ESI) is a short term for electron energy loss spectroscopic imaging. ESI is to date the most sensitive electron microscopic analytical technique and has a spatial resolution of 0.5 nm and a mass resolution of less than 50 atoms.
