CH+ is one of many molecules important in astrophysics observations and is of interest for the formation of large hydrocarbons. A key feature of work on CH+ has being its observed overabundance in the interstellar medium compared to calculated predictions. The molecular R-Matrix with Pseudo-States (RMPS) method is applied to CH+ for internuclear separations of 0.7-3.2 Angstrom using the UK Polyatomic R-Matrix codes. These calculations show the potential energy curves for the four lowest states and we identify resonances below the 3\prod threshold. We perform an initial calculation of the dissociative recombination cross sections from the resonance curves. We also detail our contributions to the UKRmol initiative, involving the creation of a consistent core of R-matrix codes.
