Drift Tube Studies of Ion-Neutral Reactions and Their Relevance to Interstellar Chemistry, gas. Some consideration is given to the variation with E. and E. of the rate coefficients, k., for ternary association reactions and to the relevance of the data in estimating radiative association rate coefficients appropriate to shocked interstellar gas.

Radiative Association,ernary) association studies yield valuable information about radiative association processes. In this review, we consider the nature of association reactions — both radiative and ternary — and discuss experimental and theoretical approaches to the determination of rate coefficients of radiative association reactions.

Conference proceedings 1988 and C2 would appear to be proIDising" P Swings and L Rosenfeld Astrophysical Journal 86,483(1937) This may have been the first attempt at modelling interstellar chemistry. As with models today, the methods used lacked reliability, but the speculation was impressive! Mark Twain might well have said

Dissociative Recombination: Polyatomic Positive Ion Reactions with Electrons and Negative Ions, point of view. It is argued that polyatomic ions are composed of valence bonds and that the dissociative recombination process normally involves the rupture of one of these bonds. This viewpoint leads to markedly different products from the predictions of previous theories. Recombination between a

Radiative Pumping and Collisional Excitation of Molecules in Diffuse Interstellar Clouds,reviewed. Particular attention is drawn to non-adiabatic coupling effects on the intensities of Lyman and Werner band systems of the vacuum ultraviolet spectrum of H. and to the role of nuclear spin on ortho-para transitions in H. due to H. collisions. The inter-relation between those processes and

Charge Transfer in Astrophysical Plasmas,ures of the collision process are analyzed within the framework of the molecular model and a brief discussion is given of the theoretical methods used to calculate the cross-sections. A comparison of recent theoretical results with the available experimental data at laboratory energies would indicat
