Comparative study of pulsed laser and fission fragment induced desorption with nucleotic compounds

Abstract

Abstract Mass spectra obtained under pulsed laser induced and fission fragment induced desorption of nucleosides and their nucleobases are reported and compared. No striking differences are observed. The nature of the excitation process for both methods is discussed. Fission fragment induced desorption is known to be due mainly to a sudden non‐resonant electric perturbation, which in conjunction with thermal activation also plays a major role in laser induced desorption.
