8 The Diffuse ISB’s NASA

9 Origin of the Diffuse Interstellar lines
Here I suggest that the lines are caused by the absorption of polyatomic molecules and that the line width is the result of radiationless internal conversion between stable states. Furthermore, I propose that the absorbing species are long chain carbon molecules, Cn, where n may lie in the range 5-15. A. E. Douglas, Nature 269, 130 (1977)

20 Adjacent Pentagon Fullerenes
One of 1812 fullerene isomers with 60 carbon atoms

21 After bucky C60, this C70 structure is the first without adjacent pentagons

26 The diffuse interstellar bands
In the original letter to Nature, we suggested that buckminsterfullerene might be a carrier of the dib’s. After enormous creative effort, John Maier’s group found two clear matches* of C60+. E.K. Campbell, M. Holz, D. Gerlich and J.P. Maier Nature. 523: 322 (2015)
