Abstract

The mesogenic dimer displaying nematic and NTB phases was
investigated by resonant x-ray scattering at both C and S
absorption K-edges and supported by the single x-ray
crystallography. In the crystal the resonant studies revealed the
forbidden reflection in non-resonant diffraction similar to that
found in the NTB phase. The lack of a second harmonic in both C
and S resonant x-ray scattering supports the double helical
structure of the twist-bend nematic phase.
