Data sets for "Structural Investigation of Sulfobetaines and Phospholipid Monolayers at the air-water interface"
Normalized neutron and X-ray reflectivity data for Langmuir monolayers composed of mixtures of dimyristoylphosphatidylcholine, DMPC and a single 18-carbon tailed sulfobetaine, SB3-18 on pure water at room temperature and at surface pressures of 15 mN/m and 35 mN/m.
Neutron measurements are carried out on D2O and air contrast matched water. Measurements were carried out with deuterated and hydrogenated lipids.

Data collection method:
Neutron reflectivity measurements were carried out on Inter at the ISIS Pulsed Neutron and Muon source at room temperature. Mixtures of DMPC and SB3-18 were investigates on D2O and air contrast matched water, ACMW. Deuterated phospholipid and sulfobetaine were used along with hydrogenated samples. X-Ray reflectivity measurements were carried out on I07 at The Diamond Light Source. As above mixtures of DMPC and SB3-18 were carried out on a water subphase at room temperature under a helium atmosphere. For both data sets are carried out at two surface pressures, the surface pressure in both cases is controlled by a Nima Langmuir trough.
Data processing and preparation activities:
Neutron reflectivity data was stitched together and normalised using Mantid software. X-Ray reflectivity data was also normalised to the critical edge and by the incident flux at the Diamond light source.
Technical details and requirements:
Reflectivity data, here given as .dat files, can be fitted and plotted using a range of programs, the Motofit package for Igor Pro, the Motofit GUI or RASCAL are some examples.
