The CO spectrum in cool giant stars is studied in detail. It is found
that CO lines show large differential shifts and asymmetries, indicating
the presence of complicated velocity fields in stellar atmospheres. It
is suggested that this finding implies that the notion of stellar
turbulence is not necessarily valid.
