The infrared spectra from 4000–250 cm−1 and the laser Raman spectra of NOAsF6, NO2AsF6, N2F3AsF6, F2NOAsF6, NOSbF6, NO2SbF6, N2F3Sb2F11, and F2NOSb2F11 are recorded. Eight of the nine fundamentals expected for the N2F3+ cation can be observed and are tentatively assigned. The vibrational spectra of the MF5 adducts are in agreement with an ionic formulation; however, the mutual exclusion rule for infrared and Raman active vibrations appears to be relaxed and one of the fundamentals v5 [F2g] is split into a doublet in almost all cases.
