  The Carina Nebula is an active star forming region in the southern sky that
is of particular interest due to the presence of a large number of massive
stars in a wide array of evolutionary stages. Here we present the results of
the spectroscopic analysis of 82 B-type stars and 33 O-type stars that were
observed in 2013 and 2014. For 82 B-type stars without line blending, we fit
model spectra from the Tlusty BSTAR2006 grid to the observed profiles of
H{\gamma} and He {\lambda}{\lambda} 4026, 4388, and 4471 to measure the
effective temperatures, surface gravities, and projected rotational velocities.
We also measure the masses, ages, radii, bolometric luminosities, and distances
of these stars. From the radial velocities measured in our sample, we find 31
single lined spectroscopic binary candidates. We find a high dispersion of
radial velocities among our sample stars, and we argue that the Carina Nebula
stellar population has not yet relaxed and become virialized.
