The electrospray ionization tandem mass spectrometric (ESI‐MS/MS) characteristics and fragmentation mechanisms of eight distamycin analogues containing N ‐methylpyrrole and N ‐methylimidazole were investigated. The members of two isomeric groups of distamycin analogues with the same elemental composition can be distinguished by MS/MS spectra of protonated molecules and of significant fragment ions.
