THE JOURNAL OF CHEMICAL PHYSICS VOLUME 53, NUMBER 3 1 AUGUST 1970 Raman spectra are reported from single crystals of graphite and other graphite materials. Single crystals of graphite show one single line at 1575 cm-1. For the other materials like stress-annealed pyrolitic graphite, commercial graphites, activated charcoal, lampblack, and vitreous carbon another line is detected at 1355 cm-1. The Raman intensity of this band is inversely proportional to the crystallite size and is caused…"F. Tuinstra, J. L. Koenig, Raman Spectrum of Graphite"
Carbon 117 (2017) 271-278 Article history: Received 30 December 2016, Received in revised form 1 March 2017, Accepted 3 March 2017 ABSTRACT During the past years one-dimensional carbon allotropes containing sp1 bonds, both individual chains and carbyne-like crystals held by Van der Waals forces, were attracting much interest. One of the recent developments is the ion-assisted condensation of sp1 chains, ordered in a hexagonal structure with nearly 5 Å interchain distance e 2D-ordered linear-chained carbon…"Buntov E.A. , Zatsepin A.F., Guseva M.B., Ponosov Yu.

February 1, 2008 Nanostructured carbon films produced by supersonic cluster beam deposition have been studied by in situ Raman spectroscopy. Raman spectra show the formation of a sp2 solid with a very large fraction of sp-coordinated carbyne species showing a long-term stability under ultra high vacuum. Distinct Raman contribution from polyyne and cumulene species have been observed. The long term stability and the behavior of carbyne-rich films under different gas exposure have been characterized showing…"L. Ravagnan, F. Siviero, C. Lenardi, P. Piseri, E. Barborini, P.
