Mechanism for odd‐electron anion generation of dihydroxybenzoic acid isomers in matrix‐assisted laser desorption/ionization mass spectrometry with density functional theory calculations
RATIONALE: Proton and radical are transferred between matrices and matrix and analyte in matrix‐assisted laser desorption/ionization (MALDI) and these transfers drive ionization of analytes. The odd‐electron anion [M–2H](•–) was generated in dihydroxybenzoic acids (DHBs) and the ion abundance of the...
