Vibration-rotation lines of C3 have been identified in the circumstellar spectrum of the obscured carbon star IRC+10216. This molecule is of interest in both the chemistry of flames, where it may be involved in the formation of soot, and in astrophysics, where it is a potential building block for carbonaceous grains. This high-resolution infrared detection of the pure carbon chain molecule C3 allows the estimation of the equilibrium C-C bond length, 1.297 angstroms. Possible astrophysical… 

The Chemistry of Cosmic Dust Analogues from C, C2, and C2H2 in C-Rich Circumstellar Envelopes.

The chemistry involved produces linear polyacetylenic chains, benzene and other PAHs, which are observed with high abundances in the early evolutionary phase of planetary nebulae, and a non-negligible amount of pure and hydrogenated carbon clusters as well as aromatics with aliphatic substitutions, both being a direct consequence of the addition of atomic carbon.

Extending the limits of rotationally resolved absorption spectroscopy: Pyrene

We report the rotationally resolved gas phase spectrum of pyrene (C16H10), which is now the largest molecule to be observed with rotational resolution using absorption spectroscopy. This represents a

Gas-phase electronic spectroscopy of highly unsaturated hydrocarbons by resonance enhanced multiphoton ionization

The electronic spectra of C 6NH2 and C8NH2 have been detected in the gas phase in the 16700–22000 cm −1 range by a mass selective resonant two-color two-photon ionization technique coupled to a laser

Preparatory work for C3 line-list calculation

The goal of this dissertation is to study the infrared absorption spectrum of the C 3 (carbon three) molecule. In particular, the aim is to investigate its ground electronic state up to 12.500 cm −1

Infrared Spectroscopy of Disilicon-Carbide, Si2C: The ν3 Fundamental Band.

The rotational levels Ka = 0 and Ka = 2 in the vibrationally excited (001) state are found to be perturbed by a Coriolis-type interaction with energetically close lying levels of the symmetric stretching and triple-excited bending mode.

Atlas of high resolution infrared spectra of carbon dioxide.

An atlas of long-path room-temperature absorption spectra of carbon dioxide is presented for the spectral intervals 1830-2100 cm, 2395-2680 cm, and 3140-3235 cm; the weakest carbon dioxide lines marked in the atlas have intensities of approximately 0.5 x 10 to the negative 26th power cm/molecule at room temperature.
