The infrared spectrum of propene in the CH stretching region is complicated by anharmonic resonance polyads associated with the coupling of CH stretch fundamentals to overtones and combinations of CHnbends and CC stretches. We report the spectra of propene isolated in both helium nanodroplets (HENDI) and solidpara-hydrogen (p-H2). Spectral assignments and anharmonic polyad memberships are obtained with a VPT2+K effective Hamiltonian. In the 2800–3120 cm−1region, the average differential matrix shift in going from HENDI top–H2is ∼4.4 cm−1to the red, with a standard deviation of 1.9 cm−1. Moreover, the choice of matrix environment influences the positions and intensity ratios of transitions within the resonance polyads. Two-state interaction models are used to confirm that differential matrix shifts less than 10 cm−1are sufficient to account for the observed differences.
