Laser Induced Breakdown Spectroscopy
. Laser Induced Breakdown Spectroscopy or LIBS has become the common acronym for element detection via laser induced plasma. This permits real-time qualitative identification of trace elements in solids, gases, and liquids via optical detection of elemental emission spectra. Using this technique, little or no sample preparation is required and calibration-free quantitative analysis has been reported without matrix effects.

Using emission spectroscopy to perform impurity analyses in UHP gases
, but of equal importance was the use of a new technique: emission spectroscopy. When excited in an electric discharge, the gases dissipated some of the energy as electromagnetic radiation at wavelengths that were specific to each gas. The spectral lines were intense enough to be easily observable
OH Emission Spectra of Hybrid Rocket Motors Using
instrumentation will become part of the rocket. motor control system to optimize thrust, fuel efficiency and safety response. To validate OH. radical information gathered from the near-infrared region using diode lasers, studies are. being conducted that measure OH radical emission spectra
vibrations specified in wave numbers (1/cm) where: Wavelength (in micrometers) = 10,000 / wave numbers. Raman scattering is a very weak effect. The strength of the Raman emission is typically a million times less than the strength of the illuminating beam. Thus measuring the Raman-scattered radiation
