The raman effect of N₂O₄. 3 SO₃ and N₂O₅. 3 SO₃

Abstract

The preparation of a compound corresponding to the formula N,O, .3 SO, is given. Neither in the manner of preparation described by In 1907 Pictet and Karl 1 ) described among other substances an addition compound of N20S with SO3, to which they ascribed the composition N , 0 5 . 4 SO:<. They obtained it by a simultaneous distillation of N,05 and SOR. (in a ratio of about l : 4 ) which gives according to Pictef and Karl the compounds N,O,. 4 SO, and A number of years ago already we decided to make a study of the first compound of Pictet c.s., in order to try to get an insight into its molecular structure. Following the technique described by Pictet and Karl -i.e. by distilling a mixture of N20B with 4 SO3 -we did not obtain the compound N,OS. 4 S0:I however, but a substance with an average composition of N z 0 4 . 3 SOR. a compound which in the following will be designed as I.
