I will present results on a variety of problems covering both collisions and spectroscopy. Electron collision studies using the R-matrix method provide a major source of electron - molecule collision cross sections for problems range from rotational excitation in the interstellar medium to dissociative processes involving radicals in technological plasmas.

An R-matrix theory has also been developed to consider ultra-low energy heavy particle collisions. In this case, the inner region is described using codes designed for the studying high-resolution molecular spectra.

These spectroscopic (nuclear motion) codes have largely been applied to predict spectra at elevated temperatures of molecules in the atmospheres of exoplanets as part of the ERC-funded ExoMol project. The use of these codes to compute temperature-dependent photodissociation rates will be discussed.
