Terahertz spectroscopy of N${}^{18}$O and isotopic invariant fit of several nitric oxide isotopologs

Holger S. P. Müller, Kaori Kobayashi, Kazumasa Takahashi +2

A tunable far-infrared laser sideband spectrometer was used to investigate a nitric oxide sample enriched in 18O between 0.99 and 4.75 THz. Regular, electric dipole transitions wer…
