16. Electronic Structures and Energy Level Alignment in Mesoscopic Solar Cells : A Hard and Soft X-ray Photoelectron Spectroscopy Study
Sammanfattning : Photoelectron spectroscopy is an experimental method to study the electronic structure in matter. In this thesis, a combination of soft and hard X-ray based photoelectron spectroscopy has been used to obtain atomic level understanding of electronic structures and energy level alignments in mesoscopic solar cells.

17. Aqueous Solutions as seen through an Electron Spectrometer : Surface Structure, Hydration Motifs and Ultrafast Charge Delocalization Dynamics
Sammanfattning : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.

18. Theoretical studies of a nanoparticle bridge platform for molecular electronics measurements
Sammanfattning : The main focus of this thesis is the theoretical investigations of a nanogap platform used for molecular electronics measurements under ambient conditions. The nanogap is about 20 nm wide, while the molecules investigated here (octanethiol(OT) and octanedithiol(ODT)) are about 1-1.5 nm long making it impossible to bridge the gap with one molecule.

19. Molecular and crystallographic aspects of some terpenoids from soft corals
Sammanfattning : The crystal structures and absolute configurations of five terpenoids:africanol, lemnacamol, capnellenetriol, sinulariolideand lobophytolide, all isolated from soft corals, have been determined by single crystal X-ray diffraction. Aspects of structure determination, conformation, absolute configuration determination and molecular association are given. LÄS MER
20. Methods of laser spectroscopy in the study of Pb₂, CaCl and CaH
Sammanfattning : Some methods of laser spectroscopy in the study of small molecules are discussed. A special emphasis is given on to how quantum number assignments can be made and rotational analyses of very dense structures can be carried out after exciting the molecules with monochromatic radiation.
