13C‐NMR and the electron impact massspectra of the β‐carboline derivatives 1 – 18 were examined. The structure of the possible diastereomers is discussed. A quantitative relationship between the relative intensity of ions a in the massspectra of 1 – 18 and the structure of substituents R was found.
