New, unexpected and largely unexplored physical phenomena occur in systems cooled to very low temperatures. The background temperature in the universe is approximately 2.7 K, but much lower temperatures have now been obtained in the laboratory. This
The relative rates at which O + CS → CO + S populates individual vibrational levels of CO have been determined (a) from infrared chemiluminescence experiments, and (b) by using a cw CO lawer to measure CO vibrational distributions produced when mix

A study has been made of the infrared chemiluminescence emitted from vibrationally excited CO formed in the reaction sequence: O + CS2→SO + CS, O + CS→CO + S, when O atoms and CS2, highly diluted in Ar, were mixed in a flow system. Relative vibra

A major aim of astrochemistry is to explain the nature and abundance of the molecules observed in the interstellar medium (ISM). Three kinds of activity are involved: (a) the spectroscopic identification of the species that are present in the ISM; (b

Information about the rate coefficients and products of processes that occur in the interstellar medium are required as input to computer models that seek to reproduce the abundances of the rich variety of molecules that have been observed in differe

The Weakness of HO 3 OH radicals play a critical role in the chemistry of Earth's atmosphere. Understanding atmospheric reaction networks thus requires an accurate knowledge of OH sources and sinks. One vexing question has been whether or not a signi

The rates of chemical reactions and the dependence of their rate constants on temperature are of central importance in chemistry. Advances in the temperature-range and accuracy of kinetic measurements, principally inspired by the need to provide data

Living entities exhibit the three fundamental characteristics of metabolism, growth and reproduction, to which we may add evolutionary adaptation to their environment. Understanding how life having these characteristics emerged on Earth within 1 Gyr

We report rate coefficients for the relaxation of OH( v = 1) by O 2 and N 2 O as a function of temperature. The rate coefficients for relaxation (in units of 10 −13 cm 3 molecule −1 s −1 ) can be fit by the following expressions: for OH ( v = 1
