High Resolution Spectroscopy

Topical Meeting on Laser Techniques for Extreme Ultraviolet Spectroscopy, 1982
High resolution spectroscopy in the vacuum ultraviolet region has, until recently, been limited to work with long focal length grating spectrographs. The best resolution with state-of-the-art instrumentation is approximately 250,000, but the photographic method provides simultaneous measurement of ≈ 3 × 104 data points with modest exposure times.

High resolution spectroscopy

TrAC Trends in Analytical Chemistry, 1983
J Michael Hollas 1982 Kent: Butterworths xv + 638 pp price £45 To write a book which covers all aspects of such a vast subject as high resolution spectroscopy is a daunting task, but one which Michael Hollas has tackled with considerable success. The author has succeeded in presenting a comprehensive description of the major branches of gas, or vapour ...

High Resolution Spectroscopy

Chemistry International, 2014
Classical high-resolution spectroscopy had been of interest for the sake of studies related to isotope shifts and hyperfine interactions and for resolving complex spectra associated with heavy elements like lanthanides and actinides. In this chapter, some of the history of classical high-resolution spectroscopy has been described.

High-resolution optical multiplex spectroscopy

Annual Meeting Optical Society of America, 1987
We have developed a frequency-multiplex laser spectrometer using the concept of stochastic excitation to provide an effective optical excitation bandwidth of >200 MHz and an inherent spectral resolution of a few kilohertz. A frequency-stabilized Ar+ laser is phase-modulated by a pseudorandom binary sequence (PRBS) running at a clock frequency of 200

High Resolution Spectroscopy

Inaugural Forum for the Research Center for Optical Physics, 1993
Water vapor is an important species in the earths atmosphere. It plays a major role in many atmospheric processes including weather, climate and atmospheric photochemistry. The distribution of water vapor in the atmosphere is highly variable and if we are to relate its variability to atmospheric effects, its spatial and temporal variability must be ...
