From: Radiative pumping vs vibrational relaxation of molecular polaritons: a bosonic mapping approach

a, b Polariton bands from the polariton absorption and transmission spectra A(ω) + 2T(ω), bare molecular absorption profile σabs(ω), and bare molecular emission profile σem(ω), for \(\sqrt{{s}_{2}}=3.5\) (a) and \(\sqrt{{s}_{2}}=5.0\) (b). c The frequency-resolved radiative pumping Γrp(ω) is proportional to the overlap between the polariton bands and the bare molecular emission. The total radiative pumping rate Γrp is the integral of Γrp(ω).
