It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down … Ver mais In 1785, Dutch chemist Martinus van Marum was conducting experiments involving electrical sparking above water when he noticed an unusual smell, which he attributed to the electrical reactions, failing to realize that he had in fact created ozone. Ver mais According to experimental evidence from microwave spectroscopy, ozone is a bent molecule, with C2v symmetry (similar to the water molecule). … Ver mais Ozone is a bent triatomic molecule with three vibrational modes: the symmetric stretch (1103.157 cm ), bend (701.42 cm ) and antisymmetric … Ver mais The trivial name ozone is the most commonly used and preferred IUPAC name.
