The recent development of a range of new methods for producing samples of gas-phase
molecules that are translationally cold (K) or ultracold (mK) is driving efforts to study reactive …

A new era in chemical kinetics was heralded 20 years ago by the results reported by
Bertrand Rowe, then at the Laboratoire d AØrothermique in Meudon.[1] Using an apparatus …

We report the release of a new version of the UMIST database for astrochemistry. The
database contains the rate coefficients of 3864 gas-phase reactions important in interstellar …

The chemistry of developing and collapsing low-mass protostellar cores is followed using a
chemical code with a time-varying density. Two evolutionary scenarios are represented …

The pulsed laser-photolysis (PLP), time-resolved laser-induced fluorescence (LIF) technique
has been used to study the reactions of the CN radical with CH 4, C 2 H 6, C 2 H 4, C 3 H 6 …

We present a comprehensive study of the physical and chemical conditions along the TMC-
1 ridge. Temperatures were estimated from observations of CH 3 CCH, NH 3, and CO …

Molecular scattering behavior has generally proven difficult to study at low collision
energies. We formed a molecular beam of OH radicals with a narrow velocity distribution …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

An entirely new experimental method is described which enables the rate constants of
neutral–neutral gas‐phase reactions to be measured at ultralow temperatures. The …

A CRESU (Cine′ tique de Re′ action en Ecoulement Supersonique Uniforme) apparatus
has been used to measure rate constants for the reactions of the ethynyl radical (C2H) with …
