THE TORSIONAL VIBRATIONS OF THE AMMONIUM IONS IN AMMONIUM IODIDE AND AMMONIUM BROMIDE [PDF]
Chemistry Letters, 1973 Abstract The far-infrared spectra of NH4I and NH4Br have been measured at temperatures of −223 to −53 °C. The torsional vibrations of the NH4+ ions in the phase III crystalline salts were observed at 301 cm−1 for NH4I at −223 °C and at 348 cm−1 for NH4Br at −166 °C.
