论文摘要
我们报告了$3ν_{2} $ of $^{14} $ nh $ _ {3} $接近4 $μm$的宽带吸收光谱。使用中型频率梳子记录了数据，该频率梳子耦合到自制的傅立叶变换光谱仪，分辨率为0.00501 $ cm^{ - 1} $。在室温下（$ t = 296 $ k）确定了六个旋转线线的线位置，线强度，自我宽度和自移参数。与Hitran 2016的比较表明，精确度提高了一致。我们实验的高精度和快速可调性使得分子气体的晚期快速光谱法。
We report the broadband absorption spectrum of the $3ν_{2}$ band of $^{14}$NH$_{3}$ near 4 $μm$. The data were recorded using a mid-infrared frequency comb coupled to a homebuilt Fourier-transform spectrometer with a resolution of 0.00501 $cm^{-1}$. Line positions, line intensities, self-broadening, and self-shift parameters for six rovibrational lines were determined at room temperature ($T=296$ K). Comparison with HITRAN 2016 shows good agreement at improved precision. The high precision and the rapid tunability of our experiment enables advanced fast spectroscopy of molecular gases.
