An RS CVn star is considered as nonsynchronous if its orbital period differs by more than 4 percent from its photometric period. Of 88 systems examined according to this criterion, 67 are synchronous, 21 are nonsynchronous. For the 21 nonsynchronous systems, it is found that their spectral types are most around KO-2 III and that their orbital eccentricities are larger and their chromospheric activity lower than the average level.
