Dataset description

Polarised Raman Spectroscopy (PRS) is used to quantify the orientational order in the conventional (N) and twist-bend (NTB) nematic phases of a homologous series of liquid crystalline dimers. The dimers investigated have 7, 8, 9 and 11 methylene groups connecting two cyanobiphenyl mesogens and data for 4-pentyl-4ʹ-cyanobiphenyl (5CB) and 4-octyl-4ʹ-cyanobiphenyl (8CB) are included for comparison. This data file includes the source data (polarised Raman spectra for the materials, deduced at various temperatures and for a series of orientation angles with respect to the input and output polarisation direction of the laser light). These spectra are in the file format produced by the Renishaw Raman microscope used, suitable for GRAMMS software. The data file also includes the depolarised Raman intensities for each of the materials at the selected temperatures as Excel files.
