    Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.

  2. 2. ROBUST DETECTION AND SPECTRAL ANALYSIS OF SIGNALS WITH APPLICATIONS IN SPECTROSCOPY

    University dissertation from Lund University

    Author : Naveed Butt; Lunds universitet.; Lund University.; [2011]
    Keywords : NQR; Detection; NMR; Raman Spectroscopy; Spectral Analysis.; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic techniques. READ MORE

  3. 3. Decay Properties and Hyperfine Interactions in Oriented Alpha-, Beta- and Gamma-emitting Nuclei

    University dissertation from Chalmers University of Technology

    Author : Mats Lindroos; Chalmers tekniska högskola.; Chalmers University of Technology.; [1993]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : The hyperfine interaction has often been described as the bridge between atomic physics and nuclear physics. On the one hand it enables us to study important nuclear phenomena which only manifest themselves in the strong internal fields originating from the surrounding electrons and on the other hand it enables us to study properties of the atomic system or of condensed matter using nuclear probes.
