在 400–700cm−1 光谱区域记录了亚硝酸 (HONO) 的高分辨率傅里叶变换吸收光谱。对于反式 HONO 异构体，根据之前的研究结果 [C.M.迪利 (Deeley)，I.M. 米尔斯 (L.O.)哈洛宁 (Halonen)，J.考皮宁 (Kauppinen)，坎。 J. Phys。 63（1985）962-965]。此外，对于丰度较低的cis-HONO异构体，首次实现了位于639.7432cm−1处的ν6带的高分辨率研究，推测ν5带位于609.2cm−1附近。对于两种异构体，在能级计算期间考虑了连接{51,61}相互作用能级的强A型和B型科里奥利相互作用。最后，使用这些结果生成了两种异构体的位置列表和实际相对线强度列表，并与一些从头开始的预测进行了比较。
High-resolution Fourier-transform absorption spectra of nitrous acid (HONO) were recorded in the 400–700cm−1spectral region. For the trans-HONO isomer a very extensive analysis of the ν5(ONO bend) and ν6(torsion) interacting fundamental bands of trans-HONO located near 595.620 and 543.879cm−1, respectively, was performed starting from the results of a previous study [C.M. Deeley, I.M. Mills, L.O. Halonen, J. Kauppinen, Can. J. Phys. 63 (1985) 962–965]. In addition, for the less abundant cis-HONO isomer, the first high-resolution study of the ν6band located at 639.7432cm−1was achieved, the ν5band is presumed to be located near 609.2cm−1. For both isomers the strong A-type and B-type Coriolis interactions linking the {51,61} interacting energy levels were accounted for during the energy level calculations. Finally, using these results a list of positions and of realistic relative line intensities has been generated for both isomers, and a comparison with some ab initio predictions was performed.
