Abstract
The real part R and the imaginary part X of the shear impedance for the nematic liquid crystal p-n-pentyl p'-cyanobiphenyl (PCB) were measured at 15 MHz. R and X are found to be equal in the nematic phase. Anisotropic viscosity coefficients are deduced from these measurements and the Rapini equality is verifiedKeywords
