Is N--O--N known to exist?

Commonly, the empirical formula $$\ce{N2O}$$ refers to the molecule with structure $$\ce{N\bond{~--}N\bond{~-}O}$$. Is the isomer $$\ce{N-O-N}$$ known to exist? I'm guessing it is significantly less stable than the NNO isomer, but that doesn't mean it's completely unknown.

• What's your definition of existing? For that, being in minimum on PES would be already something. It's existence is fleeting, at best. Jan 29 at 20:37
• I don't know what PES is, but I'd take any one paper claiming to have synthesized and characterized it as a good start on evidence.

• @zwol PES is a potential energy surface. Jan 29 at 20:47
• That you won't get. "synthesized and characterized" are wrong words. It's rather detect and that's optimistic. Jan 29 at 21:06
• Synthesized and characterized are the things that it was not. Jan 29 at 21:30
