Triglycine sulfate is one of the few genuinely second-order ferroelectric phase transitions. As for many ferroelectric phase transitions in complex and molecular systems, there is a significant order-disorder component, which is best probed using methods that are sensitive to local atomic structure. We have previously studied this transition using total neutron scattering analysed by reverse Monte Carlo simulation. However, our results show that over the temperature range for which we have data, the correlation length is so large that the simulation cell appears ordered even in the high-temperature phase. We therefore seek to collect further data at higher temperatures, in the region where the correlation length is small enough to be effectively modelled using the available Q range. Combined with our existing results, we expect these data to lead to a rapid publication.
