The radiative and photodissociative properties of the dicarbon molecule, C2, in high-lying
electronic states are of utmost importance for modeling the photochemical processes that …

The dicarbon radical, C 2, is one of the most abundant molecules in the universe, and has
been widely observed in various energetic environments. Even though numerous …

As one of the most abundant molecules in the universe, the long history of spectroscopic
studies of the dicarbon molecule, C2, reaches back two centuries. While many electronic …

We present a combined experimental and theoretical study of the threshold photoelectron
spectroscopy of the vinyl radical encompassing the first triplet excited state of the vinyl …

Aspects of covalent and ionic bonding are discussed. Common terms, such as valence,
oxidation state, and formal charge, are defined; the rules for determination of oxidation …

The low-lying electronic states of silicon dimer (Si 2) and its cation (Si 2+) have been studied
by single-photon photoelectron spectroscopy combining a flow-tube reactor, vacuum …
