 Title: DETECTION OF PROTONATED $N_{2}O$ BY DIFFERENCE FREQUENCY LASER SPECTROSCOPY Creators: Amano, T. Issue Date: 1985 Abstract: There seems to have been no spectroscopic work made on protonated $N_{2}O$, although it is well-known in mass spectrometry. Protonated $N_{2}O$ is generated in a hollow-cathode discharge through a mixture of $N_{2}O$ (15 mTorr) and $H_{2}$ (300 mTorr) in a fast flow system. An infrared absorption band around $3330 cm^{-1}$ has been observed, and at the present stage about 150 a-type R- and P-branch lines and a number of b-type Q-branch lines $(K_{a} = O - 1$ and $K_{a} = 1 - 0$) have been assigned. Two questions arise about the molecular structure. Which isomer, the O-protonated form or the N-protonated form, is more stable? Is it a well-bent molecule or a quasi-linear molecule? A tentative analysis suggests that the species detected here is an O-protonated form ($HONN^{+}$), and that it is a well-bent molecule similar to $HN_{3}$.
