The measurement of the differential velocity field in photographic plates of cool stars by means of a microdensitometer indicates that radial velocity gradients are greater for stars with larger turbulent velocities (determined by high resolution echellograms); this further implies that stellar turbulence may be related to the differential velocity field in stellar atmospheres. Stellar abundances sensitive to mixing are presently determined by high resolution Fourier transform spectroscopy, in order to serve as an observational probe of the mixing processes in red giants. The results thus obtained, together with additional data on the O-16/O-17 ratio and on CNO abundances, furnish useful constraints on the theory of mixing in red giant stars.
