(RB1010481) Neutron Compton Scattering, experiments were done on samples of poly-N-isopropylacrylamide dissolved in D2O, CH3OD and a mix of both solvents. This is of interest due to the unusual Co-Nonsolvency effect, a non-linear phenomenon which results in the appearance of a Lower Critical Solution Temperature, the lowest being at a water methanol mix of ca 65:35. RB1010481 allowed us to investigate only 6 samples. Extant understanding of the water methanol mixtures demands at least 3 main environments for the H and D nuclei. Assuming a model of only 2 sites we were able to predict the NCS widths for all the water/methanol mixtures. Observed non-zero correlations between these two sites is in agreement with the presence of a third interaction. This is a PhD project of Lee Iverson, who has to submit the thesis within six months, and futher data are needed to validate the model.
