  1. 1. Diode laser spectroscopy in extended wavelength ranges

    University dissertation from Department of Physics, Lund University

    Author : Ulf Gustafsson; Lund University.; Lunds universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diode-laser spectroscopy; frequency-modulation spectroscopy; frequency conversion; fluorescence spectroscopy; scattering; diffraction; Fysicumarkivet A:2000:Gustafsson; Atomic and molecular physics; Atom- och molekylärfysik; absorption spectroscopy;

    Abstract : Diode laser spectroscopy performed in the ultraviolet, visible and infrared spectral regions is presented. The accessible wavelength range for visible and near-infrared diode lasers is extended by the use of sum- and difference-frequency generation. READ MORE

  2. 2. Laser Absorption Spectroscopy of Gas in Scattering Media

    University dissertation from Lund University

    Author : Märta Lewander; Lund University.; Lunds universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; medical diagnosis; gas analysis; absorption spectroscopy; diode laser spectroscopy; light scattering; food-package monitoring; GASMAS;

    Abstract : Absorption spectroscopy constitutes a chemical analysis tool which can be applied to various samples and application fields. This thesis focuses on gas absorption spectroscopy with the means of diode lasers - tunable diode laser absorption spectroscopy, TDLAS. READ MORE

  3. 3. Infrared spectroscopy a tool for protein characterization

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Chenge Li; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Infrared (IR) spectroscopy, which belongs to vibrational spectroscopy, detects the vibrations of molecules, for example, proteins. The absorption of the peptide group gives rise to 9 characteristic bands in the infrared region, named A, B, I-VII, with a decreasing energy or wavenumber (cm-1). READ MORE

  4. 4. Infrared spectroscopy Method development and ligand binding studies

    University dissertation from No Idea, Could be any

    Author : Saroj Kumar; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared; Ligand binding; method development; NATURAL SCIENCES Chemistry Physical chemistry Biophysical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Biofysikalisk kemi; biofysik; Biophysics;

    Abstract : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. READ MORE
