The normal-state ESR of two new organic superconductors, {beta}{double_prime}-(BEDT-TTF){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3} and {kappa}{sub L}{prime}-(BEDT-TTF){sub 2}Cu(CF{sub 3}){sub 4}(DBCE) are reported. Both compounds showed metallic properties below 140 K. The former gave ESR line widths and g-values of 23-34 G and 2.004-2.012. The latter gave line widths and g-values of 45-58 G and 2.006-2.012. Orientation-dependent line widths and g-values of the {kappa}{sub L}{prime}-phase were found to be similar to that of the {kappa}-(ET){sub 4}Hg{sub 3}Br{sub 8} but not to the {kappa}{sub L}-phases in general.
