Notes:
The IR and Raman spectra of the mixture 4HNO3 · H2O in crystal, glassy and liquid states have been investigated in the frequency range 4000-50 cm-1. The crystal is the oxonium trihydrogentetranitrate where the oxonium ion is practically free (ν(OH) = 3480 and 3385 cm-1). In the trlhydrogentetranitrate ion the charge is not localized. In the glassy and liquid states, four species have been characterized: (1) the oxonium trihydrogentetranitrate; (2) the free molecular association H2O … (HONO2) (νOH(H2O)= 3550 cm-1 and ν OH(HNO3)=2930 cm-1); (3) the free ionic pair (H2OH)+…(ONO2)- (ν(OHO)= 2700 cm-1, ν1(NO3-)=1030 cm-1) and (4) free HNO3 molecules (ν(NOH)=926 cm-1).
