摘要: 报道了14N16O2v3带(001-000)的5组新的超高分辨激光磁共振谱线的观测,包括实验的背景、装置、方法和结果.由于利用了内腔饱和吸收情况下的兰姆凹陷和最优化的相敏调制探测技术,所得光谱的分辨率达到了微波谱量级.这些谱线是分析14N16O2乃至非对称陀螺自由基分子的塞曼效应和超精细结构特性的重要实验资料.

Abstract: This paper reports the measurement of five new sets of mid-infrared (MIR) laser magnetic resonance spectra (LMR) of the v3 band (001-000) of 14N16O2 in its ground electronic state. It details the research background, experimental apparatus, and some results obtained. With the intracavity saturated absorption technique employed and the conditions of the phase sensitive modulation detection optimized, spectra of very high sensitivity and resolution have been obtained. These spectra are eligible for studying the structure and Zeeman property of 14N16O2.
