Laser frequency-modulated (FM) spectroscopy has been used as an axial probe of a laser-guided electric discharge in sodium-argon vapor contained in an optically accessible metal heat pipe oven. Absorption measurements in the region 23 106-23 881 cm-1 provided accurate line positions (±<0.006 cm-1) for 141 transitions in the v' = 3-8 <-- v" = 0 and v' = 5-9 <-- v" = 1 bands of NaH (A1Sigma+-X1Sigma+). In addition, 18 transitions of Na (3p to 9-13d and 11-14s) and 10 of argon (5p-4s) were measured. Analysis of the spectrum indicates that perhaps all absorption signals are due to neutrals NaH, Na, and Ar and are observed via "population" modulation. Copyright 1997 Academic Press.

激光调频(FM)光谱已被用作轴向探测器,用于探测置于光学可及的金属热管炉中的钠 - 氩蒸气中的激光引导放电。在23106 - 23881厘米⁻¹区域的吸收测量为NaH(A¹Σ⁺ - X¹Σ⁺)的v' = 3 - 8 ← v" = 0和v' = 5 - 9 ← v" = 1能带中的141个跃迁提供了精确的谱线位置(±<0.006厘米⁻¹)。此外,还测量了Na的18个跃迁(3p到9 - 13d和11 - 14s)以及氩的10个跃迁(5p - 4s)。光谱分析表明,也许所有吸收信号都归因于中性的NaH、Na和Ar,并且是通过“粒子数”调制观测到的。版权所有1997年学术出版社。版权所有1997年学术出版社
