2013年12月13日 · We report the detection of gas-phase HOON in a supersonic molecular beam by Fourier transform microwave spectroscopy and a precise determination of its molecular structure by further spectroscopic analysis of its 2 H, 15 N, and 18 O isotopologs. HOON contains the longest O–O bond in any known molecule (1.9149 ± 0.0005 Å) and appears ...

Nitrosyl-O-hydroxide (molecular formula H O O N) is an isomer of nitrous acid, which has been experimentally observed in the gas phase. [2] HOON contains the longest oxygen-oxygen bond thus far observed in any known molecule, measured to be 1.9149 angstroms.

2013年12月23日 · Researchers have long known that nitrous acid (HONO) plays an important role in atmospheric chemistry. But most people dismissed the existence of the compound’s isomer, nitrosyl O-hydroxide (HOON), predicting that it wouldn’t be stable, says team leader Michael C. McCarthy.

2024年7月24日 · Here, we report the direct observation of nitrosyl-O-hydroxide (HOON) in the photochemistry of HONO, employing matrix-isolation IR and UV-vis spectroscopy. Despite a barrier of approximately 30 kJ/mol, HOON undergoes spontaneous rearrangement to the more stable HONO isomer through quantum mechanical tunneling, with a half-life of 28 min at 4 K ...

2013年1月24日 · HOON might be an elusive intermediate of atmospheric photochemical reactions of HONO or recombination of the parent nitrene HN and molecular oxygen. However, no reliable data on HOON structure and stability are available, and the nature of the O-O bond is not well understood. In this study, we used …

hoon (第三人稱單數簡單現在時 hoons，現在分詞 hooning，一般過去時及過去分詞 hooned) […] you've hooned off – it's fair to say hooned off – at quite a high speed. Cruising, hooning and street machining all involve the social use of public space where young people can exert agency by independently engaging with their surroundings.

HOON might be an elusive intermediate of atmospheric photochemical reactions of HONO or recombination of the parent nitrene HN and molecular oxygen. However, no reliable data on HOON structure and stability are available, and the nature of the O–O bond is not well understood. In this study, we used high-level single-

2013年12月13日 · Nitric oxide (NO) reacts with hydroxyl radicals (OH) in the gas phase to produce nitrous acid, HONO, but essentially nothing is known about the isomeric nitrosyl-O-hydroxide (HOON), owing to its perceived instability. We report the detection of gas-phase HOON in a supersonic molecular beam by Fourie …

HOON might be an elusive intermediate of atmospheric photochemical reactions of HONO or recombination of the parent nitrene HN and molecular oxygen. However, no reliable data on HOON structure and stability are available, and the nature of the O–O bond is …
