Laser Time-of-Flight Mass Spectrometry of PAH-Picrate Complexes

摘要

The laser desorption/laser ionization time-of-flight (L2ToF), mass spectra of anthracene and the anthracene-picric acid charge transfer(C-T) complex have been compared at a desorption and ionization wavelength of 266 nm. Laser desorption/ionization spectra of anthracene were obtained at low temperatures (-30deg) to minimize the interference from gas phase ionization.
