This is a set of high-resolution high-S/N optical spectra of the massive binary star HD 165 052 (O7Vz + O7.5Vz) taken between 2008 April and 2011 May with echelle spectrographs at CASLEO (mainly), LCO and ESO. Each one covers the spectral range 3700-6000 A with a resolution varying between ~13000 and ~45000 @ 5000A according to the instrument. Originally, the spectra were secured for radial velocity measurements. More details about observations, instrument configurations and reduction process can be found in documentation section.
