摘要

利用MARVEL程序建立了氨同位素物14NH3的经验反振动能级扩展表。最终的跃迁集包括来自97个实验源的69710个实验线位置，覆盖了18177 cm−1以下的波数范围，旋转激励高达J=29。转换集包含23844个新整理的实验转换，覆盖的能量范围超过7500 cm−1，产生10753个具有不确定性的经验能级，比之前的MARVEL研究增加了5817个。然后使用该MARVEL集对14NH3的CoYuTe线列表进行重新marvelise，产生总共641836个实验精确的线位置。更新的线路列表可从www.exomol.com获得。

Updated ro-vibrational MARVEL levels for ammonia 14NH3

An extended list of empirical ro-vibrational energy levels for the ammonia isotopologue ¹⁴NH₃ is constructed using the MARVEL procedure. The final transition set includes 69710 experimental line positions from 97 experimental sources covering the wavenumber range below 18177 cm⁻¹ and rotational excitations up to

J = 29

. The transition set incorporates 23844 newly collated experimental transitions extending the covered energy range beyond 7500 cm⁻¹, yielding 10753 empirical energy levels with uncertainties, an increase of 5817 from the previous MARVEL study. This MARVEL set is then used to reMARVELise the CoYuTe line list for ¹⁴NH₃, yielding a total of 641836 experimentally accurate line positions. The updated line list is available from www.exomol.com.
