We report on the observation of nuclear resonant forward scattering of synchrotron radiation from $\chem{^{121}Sb}$ nuclei. A temperature stabilized $\alpha$- $\chem{Al_2O_3}$ crystal Bragg backscattering high-resolution monochromator with a relative energy resolution of $2 \times 10^{-7}$ was introduced. As first spectroscopic applications the hyperfine parameters in $\chem{Sb_2O_3}$, USb and DySb were determined. The energy of the nuclear transition in $\chem{^{121}Sb}$ was measured to be $37.1298(2)\un{keV}$, 40 times more precisely than reported before. The results open the field of nuclear resonance spectroscopy on antimony compounds taking advantage of the outstanding features of 3rd-generation synchrotron sources. Nuclear resonance scattering on Sb compounds at these sources allows element-specific dynamical studies on thermoelectric materials as well as studies on magnetism in micro- and nanometer dimensional systems like spintronic devices.
