We discuss a detailed near-field spectroscopic study of the nanoscopic optical properties of a novel coupled wire-dot nanostructure grown on (31 1)A GaAs substrates. Photoluminescence spectra recorded with 150 mn spatial and 100 mueV spectral resolution pe ...
For the first time, a very general theoretical method is proposed to interpret the full electron paramagnetic resonance (EPR) spectra at multiple temperatures and frequencies in the important case of S-state metal ions complexed in liquid solution. This me ...
The detn. of residual dipolar couplings (RDCs) by quant. J spectroscopy methods such as heteronuclear single quantum correlation with phase encoded coupling (HSQC-PEC) is prone to systematic errors that may be caused by differential attenuation during the ...
Near-field photoluminescence spectra of a single quantum well dominated by emission from localized excitons are subjected to a statistical analysis of the two-energy autocorrelation function, This analysis is compared to a theoretical model of the exciton ...
Most current optical coherence tomography systems provide two-dimensional cross-sectional or en face images. Successive adjacent images have to be acquired to reconstruct three-dimensional objects, which can be time consuming. Here we demonstrate three-dim ...
In this thesis, the synthesis of oligomers of β-amino acids (β-peptides) is described. Their secondary structure is investigated by several techniques, in particular nuclear magnetic resonance (NMR) spectroscopy, but also circular dichroism and infrared sp ...
Mass selected cluster deposition is discussed with respect to three questions: what is the integrity of the clusters after deposition; are they uniform in terms of size and isomerisation; and finally what is the influence of the support on the clusters? Th ...
Autofluorescence is emerging as a useful tool for the detection of early cancers in the bronchi. It has already produced interesting results, which have been implemented in commercial imaging devices. Their design relies on the spectroscopy of the tissues ...
In situ Fourier transform infrared absorption spectroscopy has been used to study the composition of particles formed and suspended in radio-frequency discharges of silane-oxygen-argon gas mixtures. The silane gas constumption was observed by infrared abso ...
