It took five years for the principal gainsayers to accept its reality. Today, it is universally accepted, but still has not received the degree of attention that it deserves. Here, we report the syntheses of extensive series of trialkylammonium nitrates, [N0 n n *][N03], dialkylammonium nitrates, [No o n J[N03] and monoalkylammonium nitrates, [N0 o o J[N03] (1 < n < 18 in linear C„H2„+i), and a few deuteriated analogues, supplemented by selected examples of tetraalkylammonium nitrates [N0 n „ J[N03] and [N0 0 0 o][N03]. Tliese ionic liquids were studied by infrared, Raman and inelastic neutron scattering spectroscopies, DSC, 1H, 13C, 15N and 170 NMR spectroscopy, viscosity and density measurements, and (where possible) single-crystal X-ray diffraction.
