Figure 3
Wide-energy spectrum for investigation of complex solvents. The top tier shows the raw XE spectrum of the ethanol–acetonitrile mixture. The bottom tier shows the emission lines of oxygen in first and second order as well as of nitrogen from acetonitrile and carbon from both. The excitation energy was set at 540 eV which is mostly absorbed by the core electron of oxygen in ethanol. The inset shows a possible ethanol–acetonitrile configuration. The elements are colour coded in red (oxygen), grey (hydrogen), blue (nitrogen) and cyan (carbon) while the dotted lines represent hydrogen bonds. |
