WebIn this process, hydrogen leaves the layer and lowers the amount of sp 3-bonded carbons. The free bonds are converted into sp 2 hybridized carbons. Thus, re-hybridization of the carbon atom orbitals occurs. This behavior has already been observed for several polymers coated with a-C:H [8,28,29]. WebIn the case of terminal alkynes, the carbon is sp-hybridized and the C-H stretch occurs at ~3300 cm-1. The C-H stretch for sp2-hybridized carbon atoms occurs at a slightly lower frequency (3000 – 3100 cm-1). Finally, the C-H stretch for sp3-hybridized carbon atoms occurs in the 2850 – 2960 cm-1 range. 3000 cm-1 is a convenient dividing line

WebBy rationalizing the vibrational modes of various oligomers, the Raman spectrum of a 2D sp–sp 2 carbon sheet is predicted; it exhibits three sharp peaks at 2241, 1560, and 1444 cm −1. Although the target and byproducts display similar vibrational modes, a combination of Raman and infrared spectroscopies can be used to differentiate them.
