  1. 1. Time-Resolved Spectroscopy for Pharmaceutical Applications

    Detta är en avhandling från Atomic Physics, Department of Physics, Lund University

    Författare :Christoffer Abrahamsson; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elektromagnetism; optik; Near-infrared spectroscopy; Time-resolved spectroscopy; Pharmaceutical analysis; Multivariate data analysis; Electromagnetism; Light transport in turbid media; Photon migration; akustik; acoustics; optics;

    Sammanfattning : The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics.

  2. 2. Femtosecond Dynamics of Dissociation and Isomerization Reactions in Solutions

    Detta är en avhandling från Atomic Physics, Department of Physics, Lund University

    Författare :Jose-Luis Alvarez; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optics; Electromagnetism; Photochemistry; Fotokemi; acoustics; Elektromagnetism; optik; akustik;

    Sammanfattning : The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. LÄS MER
