A brief review is given of the pioneering work of Pierre during the years 1974-1981, during which time he investigated the state selective nature of electron capture by multiply charged ions under interstellar conditions. The various stages on the development of the methods used are presented: adiabatic representation and potential energy surfaces, non-adiabatic matrix elements, diabatic transformation, extraction of the S-matrix, optimal choice of reaction coordinates. Finally some very recent results on D++H2 → H++HD ion-molecule reactions inspired by the early work are presented.
