Dielectric constants and losses of N-(p-Methoxybenz)'lidene)-p-Butylaniline(MBBA) and N-(p-Ethoxybenzylidene)-p-Butylaniline (HBBA) in benzene sol tttionvv'ere ?ateasured at t]c?"ee xaaic?'owave freqt?encies (4.0, 9.4 and 30.4 GHz). Tlaedielectric relaxation tixvte (r), dipole monvent (7v) and activation enet'gy (A#j)were evalttated at 20'C to be 28.2>c]0"sec, 6.98X]0"Clll, 4.6KJ/ntole forMBBA and 36.7 sec, 7.4F3 x 10" Clll, 5.0 KJ/ncole for EBBA. The Cole-Coleplots of dielectric constants and losses were sexaaicjrcles for botla MBBA andEBBA. This fact indicates that the dielectric relaxation behaviotur of MBBA andEBBA can be discx-ibed in ternns of the xvao)ocular reorientation of rigid species
