Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film

Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...

Fundamentals of electron energy-loss spectroscopy

Electron energy-loss spectroscopy (EELS) is an analytical technique that is based on inelastic scattering of fast electrons in a thin specimen. In a transmission electron microscope (TEM) it can provide structural and chemical information about a specimen, even down to atomic resolution. This review provides an overview of the physical basis and new developments and applications of EELS in scan...

Flame Emission Spectroscopy: Fundamentals and Applications

Terahertz laser spectroscopy of the water dimer intermolecular vibrations . II

Terahertz VRT laser spectra of four ~H2O!2 intermolecular vibrations consisting of 362 transitions have been measured between 87 and 108 cm with ca. 2 MHz precision. The results differ both qualitatively and quantitatively from the predictions of dimer potentials tested. The spectra also reveal an ordering of the intermolecular vibrations which differs dramatically from that predicted by normal...

Laser Photoacoustic Spectroscopy

Fig. 7 — Principle of the photoacoustic effect. Photoacoustic spectroscopy (PAS), also known as optoacoustic spectro­ scopy, was pioneered by Alexander Graham Bell more than a century ago. The advent of the laser strongly stimu­ lated research and applications of this technique and the interest is such that international topical meetings on photo­ acoustic and photothermal phenomena are now hel...
