Using computers to design molecules is a methodology widely adopted in drug discovery to identify targets for synthesis. As molecules increase in size, more computing power is needed to work out the structure, limiting the modelling of large flexible molecules like proteins and polymers, and especially these molecules in solution. Progress has been made modelling proteins starting from known structure in the crystalline state, but for polymers (highly flexible, non-crystallising), the challenge is very much greater. The need for experimental data to develop and validate computational methods is known, but obtaining data containing sufficient detail is its own challenge. Here we will use neutron scattering methods to give detailed information on polymer solutions, from the conformation of the polymer molecule as a whole, to the interaction of segments with individual solvent molecules.
