Fig. 3
Experimental spectra in the ranges from 2.9 μm to 3.8 μm and from 6.0 μm to 7.5 μm for hydrocarbon samples (#1 to #4). The vertical dashed lines at 3.03, 3.3 and 3.4 μm bands represent the sp1 ≡ C-H stretching, the aromatic sp =C-H stretching and the aliphatic sp3 -C-H stretching, respectively. The vertical dotted lines show the difference in the 6.2 μm positions. The vertical solid lines represent the aliphatic sp3 -C-H bending at 6.94 μm and 7.27 μm.
