Abstract. We consider a complex third order differential operator
on a bounded interval
with boundary conditions presenting
a mixed aspect of the Dirichlet and the periodic problems.
It is proved that two spectra are sufficient to determine
the operator. This result is valid under readily
verifiable hypotheses applying
simultaneously to the two spectra.
