Sažetak
Infrared spectroscopy (IR) is one of the commonly employed experimental methods for the study of hydrogen sorption performance of complex hydrides, but its full power is not well recognised among researchers. It is used almost exclusively as supporting routine. However, infrared spectra give a unique insight into the system at molecular level and they are very rich in contained information. For example, detection of phase changes is enabled by simple and straightforward analysis of perturbation-dependent (where perturbation can be temperature, pressure etc.) transmission baseline, while molecular background of these transitions are obtained by the analysis of other spectral features. Furthermore, a combination of ATR and transmission technique enables a resolution of the processes in the bulk from those occuring at near-surface level. Also, IR spectroscopy is well recognised as one of the most powerful experimental techniques for investigation of hydrogen bonding. The power of this technique will be illustrated here on the example of dehydrogenation of ammonia borane, where IR spectroscopy gives a unique insight in dihydrogen bonding and shed a light into important, but previously oversought mechanistic pathways.
