已通过 N2-xH2dc 流动放电中的激光诱导荧光 (LIF) 检测到 N、H 和 NH 活性物质的密度。在放电后条件下（Δ∼0.05 秒，p = 2 托），N 原子密度在 x = 0.2–0.5% 处出现峰值，H 原子密度在 x = 1% 和 90% 之间出现平台值。 N 原子的 LIF 测量结果与 N2(B, v = II) 布居趋势的比较表明，该态的发射可用于监测 N 原子。仅在放电区域内检测到 NH 自由基。
Densities of N, H, and NH active species have been detected by laser-induced fluorescence (LIF) in N2-xH2dc flowing discharges. A peak value of N atom densities far x = 0.2–0.5% and a plateau value of H atom densities between x = 1% and 90% in post-discharge conditions (Δ∼0.05 sec, p = 2 torr) has been found. Comparison between LIF measurements of N atoms and the trend of the N2(B, v = II) population shows that the emission from this state can be used for monitoring N atoms. The NH radical has only been detected inside the discharge region.
