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

    Author : Saroj Kumar; Andreas Barth; Janos Mink; []
    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

  2. 2. Infrared studies : Method development and binding of ligands to pyruvate kinase

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

    Author : Saroj Kumar; Andreas Barth; Christopher Wharton; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; Biophysics; biofysik;

    Abstract : Infrared spectroscopy is a valuable technique for the study of ligand induce change in biomolecules. Our development of a dialysis accessory to attenuated total reflection infrared spectroscopy makes this technique more universal for ligand binding studies. READ MORE

  3. 3. Vibrational Spectroscopy of Surface Adsorbates on Metal Surfaces. Experiments and Calculations

    University dissertation from Ragnar K. Ásmundsson, Chemical Physics, Lund University

    Author : Ragnar K Ásmundsson; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio electronic structure calculations; Fermi resonance; vibrational spectroscopy; Reflection absorption infrared spectroscopy; Fourier transform infrared spectroscopy; Cu 100 and W 110 single crystal surfaces; Physics; Fysik;

    Abstract : This work deals with a detailed analysis of the vibrational spectra of methoxy (CH3O-) and ethoxy (CH3CH2O-) on W(110) and Cu(100) single crystal surfaces. By using theoretical ab initio quantum mechanical modeling, it is demonstrated that an unprecedented quantitative understanding of the vibrational frequencies of a surface adsorbate can be obtained.

    University dissertation from Martin Andersson, Östervång 30, 247 32 Södra Sandby, Sweden

    Author : Martin Andersson; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gränsskikt; anharmonicity; Ytkemi; Surface and boundary layery chemistry; adsorbates; metal surface; density functional theory; first-principle calculations; electron spectroscopy; reflection-absorption infrared spectroscopy; vibrational spectroscpy;

    Abstract : This work deals with interpretation of experimental surface spectroscopic data with the aid of first-principle calculations. Surface infrared reflection-absorption spectra as well as spectra from the electron spectroscopic methods photoemission and X-ray absorption are considered. READ MORE

  5. 5. Vibrational Sum Frequency and Infrared Reflection/Absorption Spectroscopy Studies of the Air/Liquid and Liquid/Metal Interfaces

    University dissertation from Stockholm : KTH

    Author : Magnus Johnson; Christofer Leygraf; Andrew Gewirth; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion science; laser spectroscopy; nonlinear optics; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Atmospheric corrosion, the most common form of metal corrosion, occurs within the interfacial region between a solid, and the surrounding atmosphere. In fact three phases and two interfaces are involved: the gas, a thin liquid layer, a solid, the gas/liquid and the liquid/solid interfaces. READ MORE
