The ratio of nuclear quadrupole moments of the first excited state with respect to the ground state in /sup 99/Ru has been determined from Mossbauer effect measurements with single crystal absorbers of ruthenocene. The result, Q/sub 1//Q/sub 0/=2.93+-0.07, when combined with a recent measurement of Q/sub 0/ gives the value Q/sub 1/=0.23x10/sup -24/ cm/sup 2/. An improved value for the E2/M1 amplitude mixing ratio, delta=-1.56+-0.02 is determined from magnetic hyperfine spectra obtained with an absorber of ruthenium disolved in iron. A determination of the angle between the axis of the electric field gradient and each of the three crystal axes of ruthenocene is in good agreement with the crystal structure reported for this compound. The recoil-free fraction was found to vary with respect to orientation of the crystal axes by a factor of greater than 2. (AIP)
