Zusammenfassung:ABSTRACT One of the basics of astrophysics is the construction of a theory to explain tidal interactions and evolution. The accuracy of the theoretical models produced by these theories is relied upon by various other astrophysical fields. As a result, putting observational models to the test is of utmost importance. The foundation of this premise rests on the comparison between predicted models and observed stellar quantities. In order to maximize the potential of the topic, a comprehensive analysis of five massive eccentric binary systems is presented in this study, which is further compared with other sample sets to evaluate the impact of tidal interaction in massive eccentric systems. The amalgamation of radial velocity measurements with photometry has yielded a comprehensive collection of both physical and orbital parameters. The spectra of each binary system were evaluated using a standard atmospheric analysis in order to ascertain the temperatures and metallicities of each component in the binaries. The utilization of high-precision analysis enables us to ascertain the evolutionary status of the components that have been deduced from models of stellar evolution, by examining the positions of these components in the T$_{\rm eff}/\log g\,{\rm Kiel}$ diagram. The examination of the influence of tidal interaction on stars possessing radiative envelopes constitutes an important part of our research. The interpretation of our analysis is situated within the framework of the temporal scales of tidal synchronization and circularization.
