On the Structure, Magnetic Properties, and Infrared Spectra of Iron Pseudocarbynes in the Interstellar Medium

Authors: Pilarisetty Tarakeshwar, Peter R. Buseck, and F. X. Timmes

Caption: Figure 2.

Comparison of the IR spectra of C₉NH and different sizes of C_nH₂ (n = 2, 4, 6, 8, 10) polyynes. Polyynes of all lengths are characterized by an IR-active C–H stretching mode at λ ∼ 3 μm, and an IR-active CCH/CCC bending mode at λ ∼ 16 μm. In C₂H₂, the bending mode appears at λ ∼ 13 μm.
