Are Nitogen Dioxide (NO2) & Nitrogen Peroxide (NO2) one & the same?




No, they are not the same. A compound is called peroxide when they contains the peroxide bond ($\ce{-O-O -}$). However, in this context, nitrogen peroxide can be considered an equilibrium mixture of nitrogen dioxide and dinitrogen tetroxide in varying proportions. The first mention of this "compound" was in this [1944 paper](https://www.nature.com/articles/153408a0), but not sure how accurate the information is in here considering an erratum has been published for this paper.
