- Abstract summary: We show that most features in 2D-IR spectra of vibrational polaritons can be explained by a linear superposition of this background signal and the true polariton response.
There are many potential applications of "polaritonic chemistry," ranging from modified chemical reactivity to quantum in-formation processing.

- Abstract: Strong coupling between vibrational transitions in molecules within a
resonant optical microcavity leads to the formation of collective, delocalized
vibrational polaritons. There are many potential applications of "polaritonic
chemistry," ranging from modified chemical reactivity to quantum in-formation
processing. One challenge in obtaining the polaritonic response is to remove a
background contribution due to the uncoupled molecules that generate an
ordinary 2D-IR spectrum whose amplitude is filtered by the polariton
transmission spectrum. We show that most features in 2D-IR spectra of
vibrational polaritons can be explained by a linear superposition of this
background signal and the true polariton response. Through a straightforward
correction procedure, where the filtered bare molecule 2D-IR spectrum is
subtracted from the measured cavity response, we recover the polaritonic
spectrum.

Exploiting this phenomenon affords the possibility of using photoinduced triplet states in porphyrins for quantum information as a resource to polarize and magnetically couple molecular electronic or nuclear spin qubits and qudits.
