dc.description.abstract	We report measurements of the temperature variation of the flexoelectric coefficient (e1-e3) of a number of nematic liquid crystals like phenylcyclohexanes, cyanobiphenyls, etc. We have also measured (e1+e3) of a few systems using appropriate methods of applying an electric field gradient to the sample. In most of the systems, (e1-e3)/k, where k is a curvature elastic constant, is found to be positive and independent of temperature, as expected. However, in 4-heptyl-1-(4-cyanocyclohexyl)cyclohexane and a few other compounds with relatively flexible parts, \|(e1-e3)/k\| increases with temperature. We discuss the possible molecular origin of the sign and temperature dependence of the flexoelectric coefficients of the systems studied.	en
