Abstract Solutions containing several nitrogen oxide species have been investigated in liquefied argon in the temperature range 84–105 K, and in liquefied kyrpton in the temperature range 116–150 K, using infrared spectroscopy. The following nitrogen oxide species were characterised in these solutions: NO, cis -ONNO, trans -ONNO, the asymmetric dimer ONON, asymmetric ONNO 2 , symmetric ONONO and N
摘要 已经使用红外光谱研究了在 84-105 K 温度范围内的液化氩气和 116-150 K 温度范围内的液化氪气中含有几种氮氧化物的溶液。在这些溶液中表征了以下氮氧化物种类:NO、顺式-ONNO、反式-ONNO、不对称二聚体ONON、不对称ONNO 2 、对称ONONO和具有D 2h 对称性的N 2 O 4 。NO 二聚化为顺式-ONNO 的焓已在液化氩气中测定为-14.3±1 kJ mol -1 。
