This thesis will focus on the experimental results obtained from the use of a very intense source of far-infrared radiation to investigate the low frequency dynamics in a number of hydrogen bonding liquids and hydrogen bonding liquid mixtures. The aim of this work is to gain a deeper understanding about the microscopic mechanisms that contribute to the resonances observed in the far-infrared spectra of these liquid systems. Furthermore, it attempts to extend the knowledge gained from the study of simple liquids, to begin to understand the low frequency motions of a more complex set of liquid systems, mainly that of biological molecules. |
