摘要：

The **2**5**2Cf plasma desorption mass spectra of 21 biologically active polymethylenediamine-linked encephalin analogs are discussed in detail. Reasonable fragmentation pathways are easily discerned in the unblocked members of the series and redundant molecular weight information is available from all substances studied. Invariably the (M plus H)** plus or (M plus Na)** plus are the most intense ions at higher mass and the technique is recommended for confirming structure during peptide synthesis.
