Development of laser ionization tools toward study of spectroscopy and dynamics of molecules relevant to combustion processes. Ionization versus dissociation was studied in CO{sub 2}; the intensity dependence of vibrational structure in photoelectron spectra had no changes over almost a 2{times} factor, indicating that the CO{sub 2} multiphoton ionization through its Rydberg states proceeds by autoionization of bound, neutral dissociative states at the four photon level. Variants of threshold ionization spectroscopy were used for studying ions, aromatics, diazines, azines, etc. In collaboration with BNL people, rotational structure of the combustion radicals trans-HOCO and DOCO, and vacuum uv photodissociation of three chlorofluoromethanes were studied.
