The stabilities of the free radicals obtained considerably exceed stability of the diphenylpicrylhydrazyl radical.enвердазилиформазанитетразінипентафлуорфенільні замісникивердазилыформазанытетразиныпентафторфенильные заместителиverdazylsformazanestetrazinespentаfluorphenyl substitutentsкафедра харчової хіміїArticle
