Abstract : The purpose of this work is to develop techniques to overcome the fundamental limits of present frequency standards---the second order and residual first-order Doppler shifts. Suitable frequency reference transition are studied in ions which are stored on electromagnetic traps and cooled by radiation pressure to 1K. Keywords: Atomic spectroscopy; Doppler narrowing; Doppler shifts; Frequency standards; High resolution spectroscopy; Ion storage; Laser spectroscopy; Penning trap; Radiation pressure.
