title: Energy and metastable characteristics in peptides. 1-Metastable/daughter ion ratios as an aid in peptide sequencing.
abstract: The metastable/daughter ion ratios, [m*]/[D+] values were measured in the first field free region. The [m*]/[D+] values were found to be influenced by the amino acid sequence in peptide molecules.
