  1. 1. Infrared spectroscopy a tool for protein characterization

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Chenge Li; Andreas Barth; Silvia Maria Doglia; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : 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). LÄS MER

    Detta är en avhandling från No Idea, Could be any

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

    Sammanfattning : 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. LÄS MER

  3. 3. Diode laser spectroscopy in extended wavelength ranges

    Detta är en avhandling från Department of Physics, Lund University

    Sammanfattning : The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. LÄS MER
