The number of OB stars is the most basic quantity to characterize massive star clusters. We studied several massive clusters using Chandra X-ray observatory and found 30--80 new OB star candidates in RCW49, NGC3603, and NGC3576. The numbers are about 2-3 times larger than those previously known and their spatial distribution extends beyond the central OB associations. We propose a multi-object spectroscopy of these sources to confirm their nature. Using hydrogen and helium emission/absorption lines in the 4000-5000 A spectra and comparing with the OB spectral atlas in the literature, we can determine spectral subtypes and luminosity classes of these sources.
