11. Internal rotation in molecules : a nuclear magnetic resonance relaxation study
Abstract : In order to study the internal rotation of methyl-type groups in molecules, the carbon-13 nuclear magnetic resonance (NMR) spin-lattice relaxation times (T1) and nuclear Overhauser enhancement factors (n) are measured for some terpenes (borneol, camphor, isopinocampheol and α-pinene), for octafluorotoluene and for 1-methylnaphtalene. In addition, deuterium NMR T1 data are presented for 1-methylnaphtalene-d10. READ MORE

14. Synchrotron radiation studies of gas phase molecules : from hydrogen to DNA sugars
Abstract : This thesis summarises experimental results on the molecular spectroscopy of gas phase molecules excited by synchrotron radiation in the VUV and soft X-ray regions. We have used three different detection techniques, photon induced fluorescence spectroscopy, photoionisation mass spectroscopy and near edge X-ray absorption fine structure spectroscopy to study molecular deuterium, hydrogen sulphide, ammonia, methanol, pyridine, pyridazine, pyrimidine, pyrazine, s-triazine, and 2-deoxy-D-ribose, the last one also known as the DNA sugar.
