| Abstract: | We present a program for observations of spectroscopic binaries with VLTI. The aim of such observations is to obtain high
accuracy measurements of stellar parameters, in particular masses, combining the visual orbit with spectroscopic orbital elements.
We selected a sample of spectroscopic binaries, including pre-main sequence stars, using the estimated angular nodal separation
as a criterion for feasibility. A cross-check with the 4th catalog of measurements of binary stars (Hartkopf, 2001) was carried
out and we discuss the statistical properties of the sample.
