Abstract
Infrared spectra of 2–5 μ are reported for NH4(NH3)n+, n=0 to 4. The ν3 mode is found at 3335 cm−1 in NH4+, 2867 cm−1 in NH4(NH3)4+. The ν3′ modes in NH4(NH3)3+ are found at 2682 and 3365 cm−1 and the ν1′ mode is found at 2790 cm−1. The overtone band 2ν4 is observed at 3087 cm−1 in the n=4 species and 3000 cm−1 in the n=3 species. Isotope effects are reported. Less detailed spectra are reported for n=1 and n=2 species.Keywords
