Plasmonic chemistry is an emerging field that seeks to uncover new pathways for chemical reactions. One intriguing phenomenon in this domain is the strong coupling between a plasmonic cavity field and molecular excitations, resulting in the formation of hybrid polariton states. These hybrid states can modify potential energy surfaces and potentially tune material properties to benefit from enhanced reaction rates. To deepen our understanding of polariton dynamics, we investigate an analogous system where molecular vibrational resonances hybridize with an IR Fabry-Pérot cavity field mode. In this work, we present a detailed analysis of vibrational cavity strong coupling under angular variation, including the shift in polariton energy as the cavity is tilted. Additionally, we explore the polariton composition (Hopfield coefficients) and predict transmission, reflection, and absorption spectra. Our goal is to compare these theoretical results with pump-probe experiments, thereby contributing to a more comprehensive understanding of strong coupling dynamics.
