摘要: Abstract Molecular motion of the ammonium ion has been investigated by IR spectroscopy in a series salts which have reported to be weakly hydrogen-bonded. Infrared spectra Isotopically isolated NH 3 D + 4 ClO , and BF recorded between 295 22 K. Broadening N-D stretching bands, each case, is attributed short residence time indicates rapid reorientation ion. The band broadening persists down lowest temperature. BPh SO F, Me PF 6 90 No significant lifetime found these salts.
