Conclusions
1. The results of a study of the fragmentation of substances (I)-(IX) under the conditions of mass spectroscopy have confirmed the positions of the side-chain nitrogen atom and the ethereal oxygen.
2. When the functional groups in position C1 in the molecules of substances (I)-(IX) change, the main fragments remain the same for all the compounds studied and specific fragments appear for each compound.
3. A possible scheme of fragmentation is given for substances (I)-(IX).
