## Abstract Matrixβassisted laser desorption/ionization (MALDI) was performed using two pulsed lasers with wavelengths in the IR and UV regions. A 10.6 Β΅m pulsed CO~2~ laser was used to irradiate a MALDI target, followed after an adjustable delay by a 337 nm pulsed nitrogen laser. The sample consis

## Abstract A quantitative model of primary ionization in ultraviolet matrixβassisted laser desorption/ionization (UVβMALDI) is presented. It includes not only photochemical processes such as exciton pooling, but also the effects of the desorption event. The interplay of these two is found to be a
A scheme of matrix ionization in UV matrix-assisted laser desorptiodionization is presented. Excitation to an upper lying electronic singlet state by the absorption of two photons and subsequent thermionic emission by vibronic coupling is proposed as the primary route for the formation of unprotonat
