Context. Interstellar molecules are excellent tools for studying the physical and chemical environments of massive star-forming regions. In particular, the vibrationally excited HC3N (HC3N*) lines are the key tracers for probing hot cores environments. Aims. We present the Atacama Large Millimeter/submillimeter Array (ALMA) 3 mm observations of HC3N* lines in 60 hot cores and investigate how the physical conditions affect the excitation of HC3N* transitions. Methods. We used the XCLASS for line identification. Under the assumption of local thermodynamic equilibrium, we derived the rotation temperature and column density of HC3N* transitions in hot cores. Additionally, we calculated the H-2 column density and number density, along with the abundance of HC3N* relative to H-2, to enable a comparison of the physical properties of hot cores with different numbers of HC3N* states. Results. We have detected HC3N* lines in 52 hot cores, 29 of which show more than one vibrationally excited state. Hot cores with higher gas temperatures have more detections of these vibrationally excited lines. The excitation of HC3N* requires dense environments, and its spatial distribution is affected by the presence of UC HII regions. The observed column density of HC3N* contributes to the number of HC3N* states in hot-core environments. Conclusions. After analyzing the various factors influencing HC3N* excitation in hot cores, we conclude that the excitation of HC3N* is mainly driven by mid-IR pumping, while collisional excitation is ineffective.
