摘要

在n = 2,3和4,X = Br, Cl或NMe2的情况下，利用电子冲击离子源和半对数图法测定了N3P3FnX6−n的电离能。结果与N3P3X6的值进行比较，其中X = Br, Cl, F或NMe2。在N3P3F6中用二甲氨基取代氟导致电离能显著降低。类似但不那么明显的减少发生在氟被溴或氯取代时。测定了几个碎片离子的表现能。

Electron impact ionisation energies of some halo-cyclotriphosphazenes

Ionisation energies have been determined for N₃P₃F_nX_6−n where n = 2, 3 and 4 and X = Br, Cl or NMe₂, using an electron impact ion source and the semi-logarithmic plot method. Results are compared with values for N₃P₃X₆ where X = Br, Cl, F or NMe₂. The substitution of dimethylamino groups for fluorines in N₃P₃F₆ causes a marked decrease in ionisation energy. A similar though less pronounced decrease occurs on substitution of fluorine by bromine or chlorine. The appearance energies were determined for several fragment ions.
