WebApr 15, 2024 · Figure 1 shows the Raman spectra of tribofilms produced on SS during VPL of methylcyclopentane [].When irradiated with a low power laser (0.41mW) at 532 nm (= 2.33 eV photon energy, Fig. 1a), the tribofilm showed a large fluorescence background and negligible D- and G-bands. The fluorescence background means that the tribofilm absorbs … WebThere will be two layers that can be separated by the funnel, aqueous and organic, which will consist of NaOH and HCl and the organic layer will be made up of methylene chloride. Two other techniques, H NMR and IR spectroscopy will be used to help identify the unknown acidic component of this experiment.
