Synopsis Circularly polarized high-order harmonic generation in molecules by bicircular pulses has been studied. We describe the laser induced electron dynamics in a rotating frame. The Coriolis effects give rise to orthogonal polarization harmonics. It is found that harmonic property depends on pulse frequencies and helicities, molecular orbital symmetries, and electron localizations, illustrating the importance of the field-molecule symmetry. The feature is described by dynamical symmetry theory and time profile analysis of harmonics.
