Web7. máj 2024 · An increase in alkyl chain length suppresses the formation of the n = 1 phase (and consequently higher n phases), which is attributed to the change in the packing arrangement of spacer cations from parallel (one and two carbon atom alkyl chains) to non-parallel (3 carbon atom alkyl chains). WebSpace chemistry is a relatively recent area of specialisation compared to astrophysics. Atoms and molecules are not very abundant in space and their average temperature is very low. Molecular collisions that result in chemical change are rare but, given enough time, complex molecules can form.
