Infrared spectra ( band) of several stars located in the region of theDBS 113 cluster were obtained using simple dispersion. The study ofthese data revealed that most of them would be of an early spectral type(OB). This information was supplemented with photometric multi-band data(VPHAS+, 2MASS and VVV), HI line data in radio (SGPS) and informationfrom the literature. As a result of the study, we found differencesbetween the spectrophotometric distance obtained from optical andinfrared data, and with the kinematic distance from HI data. Thesediscrepancies revealed the existence of particular behaviors in theinfrared spectral distributions of early spectral type stars, and thelimitation of the kinematic model in this direction. On the other hand,taking into account the spectrophotometric distance, the energy of themore massive stars allowed to explain the ionization of the HII regionRCW 116B.
