| Abstract: | Three infrared absorptions are assigned to AlF3 isolated in solid argon: ν2 = 286.2 cm?1, ν3 = 909.4 cm?1, and ν4 = 276.9 cm?1. The multiplet pattern previously reported near 950 cm?1 is not present in carefully isolated AlF3. Our spectra do not conclusively rule out a pyramidal structure for AlF3; however, no infrared absorptions can be confidently assigned to ν1, the symmetric stretch. |
