Royer et al. (2007) showed that the distribution of rotational velocities for A0-A1 stars isbimodal although all known peculiar and/or binary stars had been excluded from their sample. We presenthere the preliminary results of the abundance analysis for 47 A0-A1 \normal" main sequence stars selectedwith v sin i slower than 65 km s􀀀1. These high signal-to-noise spectra collected with ELODIE and SOPHIE(OHP) will allow us to obtain a clean sample of low v sin i normal A0-A1 stars and search for intrinsic slowrotators.
