MORE than a hundred well-defined absorption bands, arising from diffuse gas in the interstellar medium, have been observed in the visible and near-infrared spectra of stars 1–4. The identity of the species responsible for these bands has remained unclear, although many possibilities have been suggested5,6. Carbon-based molecules ubiquitous in the interstellar medium have been widely favoured as potential carriers of some of the diffuse interstellar bands7–10,29; in particular, C60+ has been… 

Laboratory confirmation of C60+ as the carrier of two diffuse interstellar bands

The diffuse interstellar bands are absorption lines seen towards reddened stars. None of the molecules responsible for these bands have been conclusively identified. Two bands at 9,632 ångströms and

Laboratory confirmation of C 60 1 as the carrier of two diffuse interstellar bands

The diffuse interstellar bands are absorption lines seen towards reddened stars. None of the molecules responsible for these bands have been conclusively identified. Two bands at 9,632 ångströms and

IDENTIFICATION OF NEW NEAR-INFRARED DIFFUSE INTERSTELLAR BANDS IN THE ORION NEBULA

Large organic molecules and carbon clusters are basic building blocks of life, but their existence in the universe has not been confirmed beyond doubt. A number of unidentified absorption features

Perspective: C60+ and laboratory spectroscopy related to diffuse interstellar bands.

Though many species were found to have electronic transitions in the visible where the majority of diffuse bands are observed, none of the absorptions matched the prominent interstellar features and in 2015, the first carrier molecule was identified: C60+.

Confirming Interstellar C60+ Using the Hubble Space Telescope

Recent advances in laboratory spectroscopy lead to the claim of ionized Buckminsterfullerene (C ) as the carrier of two diffuse interstellar bands (DIBs) in the near-infrared. However, irrefutable

IDENTIFICATION OF MORE INTERSTELLAR C 60 + ?> BANDS

Based on gas-phase laboratory spectra at 6 K, Campbell et al. confirmed that the diffuse interstellar bands (DIBs) at 9632.7 and 9577.5 Å are due to absorption by the fullerene ion C 60 + . ?> They

The Search for Interstellar C60

The optical region of a number of reddened O-type stars has been examined on Keck I HIRES spectrograms (R = 45,000) for evidence of interstellar C60. No absorption features were detected near the

On the identification of the C+60 interstellar features

The identity of the carriers of the diffuse interstellar bands (DIBs) is one of the most fascinating puzzles of modern spectroscopy. Over the last few years the number of known DIBs has grown

The identification process is reviewed placing special emphasis on the laboratory studies which have enabled spectroscopic measurement of large cations cooled to temperatures prevailing in the interstellar medium, providing the first answer to the problem of the diffuse interstellar bands.

The diffuse interstellar bands - a brief review

The diffuse interstellar bands, or DIBs, are a large set of absorption features, mostly at optical and near infrared wavelengths, that are found in the spectra of reddened stars and other objects.
