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 … WebThe NIST Quantitative Infrared Database currently consists of a collection of absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST. Spectra are provided in 5 resolutions from 2.00 cm −1 to 0.125 cm −1 using 5 apodization functions.
