Surface nitrogen abundances (log (N/H) + 12) by mass vs. projected rotational velocity (v sin i) for the O-type stars analyzed in N11 B. Most of the objects are nitrogen-enriched by up to a factor of seven. A standard nitrogen abundance in the LMC (log(N/H) + 12 = 6.88) is indicated as a reference. With a median value of v sin i = 100 km s⁻¹, none of the stars are considered slow or fast rotators. The non-rotational broadening for each star (v_mac) is also indicated with an empty circle. No trend is apparent. Typical uncertainties are indicated.
