CH 拉伸区域中丙烯的红外光谱由于与 CH 拉伸基本原理与泛音的耦合以及 CHnbend 和 CC 拉伸的组合相关的非谐共振多聚体而变得复杂。我们报告了在氦纳米液滴 (HENDI) 和固体仲氢 (p-H2) 中分离出的丙烯的光谱。使用 VPT2+K 有效哈密顿量获得谱分配和非调和多元子隶属度。在 2800–3120cm−1 区域,从 HENDI top–H2 到红色的平均微分矩阵位移为 ∼4.4cm−1,标准差为 1.9cm−1。此外,基质环境的选择影响共振多聚体内跃迁的位置和强度比。两种状态相互作用模型用于确认小于 10cm−1 的微分矩阵位移足以解释观察到的差异。
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.
