Remarks on the Chemical Conditions on the Surface of the Primitive Earth and the Probability of the l field of the Earth. About 10. atoms of carbon reacted with water during less than 10. s. The crucial question is whether some form of life will always develop under these conditions, or whether the origin of life is an improbable, perhaps an immensely improbable event. At present it is still impossible to answer this question.

Molten Earth and the Origin of Prebiological Moleculesanic gas suggests the following possibilities:.In an appendix, it is argued, on the basis of the observational evidence of the exospheric temperatures of planets by space probes, that a highly reducing atmosphere would (if it existed on the primitive Earth) have disappeared very quickly due to the thermal escape of hydrogen from its exosphere.

Quantum Chemical Study of the Thermodynamics, Kinetics of Formation and Bonding of H2CN: Relevance tfavored over IIA. Calculated properties of the minimum energy conformers of I and IIA are described and the potential role of H.CN (I) as a reactive intermediate in prebiotic organic synthesis and its possible relevance to interstellar organic chemistry are discussed.
