Dataset description
We report polarised Raman spectroscopy and dielectric properties of an asymmetric bent-core compound derived from 3-hydroxybenzoic acid with a long terminal chain at one end and a nitro group at the other. This data file includes 2 sections: 1) polarized Raman data: including the source data (polarized Raman spectra for the liquid crystal 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) and the depolarization Raman intensities data as Excel files. 2) Dielectric spectroscopy data: including the perpendicular and parallel component of dielectric permittivity (real part) as function of temperature, dielectric permittivity (both real and imaginary parts) change at different frequency and the source data.
