Organic compounds present in the Murchison (C2M) and Allende (CV3) carbonaceous chondrites were examined using surface analysis by laser ionization (SALI), a new photoionization mass spectrometic technique capable of subfemtomole sensitivity on very small samples. The analyses utilized three techniques: (1) thermal desorption combined with single-photon ionization using 118-nm light (SALI-118); (2) thermal desorption and resonantly enhanced multiphoton ionization using 266 nm light (SALI-266); and (3) stimulated desorption with 7 keV Ar(+) and SALI-118 nm. The use of SALI-118 and SALI-266 made it possible to identify alkanes and alkenes, aromatic compounds, organosulfur compounds, elemental sulfur and sulfides, and chlorobenzenes in both meteorites. However, carboxylic acids and amino acids were not well represented in the organic SALI spectra relative to their known abundances in these samples.
