| contents | This letter demonstrates the formation of vibro-polaritonic states by strong coupling gaseous nitrous oxide molecules at room temperature. The ro-vibrational features of the molecule is utilized to understand the nature of the strong light-matter interaction in the gas phase. Mixing of the P and R-branch population gives three polaritonic branches, and the dispersion experiments are well supported by three coupled oscillator model. The best mixing of the ro-vibrational population occurs for the middle vibro-polaritonic state, which is formed at the place of the Q-branch (which is otherwise not allowed in the uncoupled system). Further, the Boltzmann distribution is also altered in the strong coupled system. High-resolution spectroscopic studies suggest the presence of a large uncoupled population along with the newly formed vibro-polaritonic states. The gas phase vibrational strong coupling on small molecules proposed here is one step closer to understanding the rate modification in polaritonic chemistry experiments. |
