The study of pure carbon molecules has engaged great interest for many decades. 1
Molecules of this kind were first detected in astrophysical sources over a century ago and …

Ever since matrix isolation spectroscopy was used as an analytical tool, carbenes and
related species have been a target of this method. Early reports on reactions of methylene in …

Ultraviolet photoelectron spectra (UPS) of negative carbon clusters are reported in the size
range from 2 through 29 atoms. The clusters were prepared in a supersonic beam by laser …

SINCE their discovery over 40 years ago, the origin of the diffuse interstellar absorption lines
has been a mystery although there have been many suggestions put forward. Developments …

Anion photoelectron spectroscopy has been employed to obtain vibrationally resolved
spectra of the carbon molecules C2–C11. The spectra of C− 2–C− 9 are dominated by linear …

The vibrational spectrum of the linear carbon clusters C2− C9 and of cyclic C4, C6, C8, and
C10 has been investigated using the augmented coupled-cluster, CCSD (T), method and …

The cyclocarbons constitute a family of molecular carbon allotropes consisting of rings of two-
coordinate atoms. Their high reactivities make them difficult to study, but there has been …

The structure of 20-atom carbon clusters has been studied using correlated ab initio
calculations with large basis sets. SCF calculations predict a monocyclic, poly-acetylene …
