The left should get themselves a new hero-nation. Try Cuba. There’s also the old stereotype. The “yellow rain”, it turned out, was pollen-laden feces dropped by huge

Infrared spectroscopy is a sensitive probe for the presence of bridging carbonyl ligands. For compounds with doubly bridging CO ligands, denoted μ 2-CO or often just μ-CO, ν CO, ν CO is usually shifted by 100–200 cm −1 to lower energy compared to the signatures of terminal CO, i.e. in the region 1800 cm −1.Bands for face capping (μ 3) CO ligands appear at even lower energies.
