Solid-state NMR spectroscopy and other techniques have been used to make an inventory of the insoluble organic molecules found in the Sutter's Mill meteorite that may reflect the chemical resources available to the early Earth. Details of the NMR and gas chromatography-mass spectrometric analyses released upon hydrothermal treatment of a sample from the meteorite are reported in the journal Proceedings of the National Academy of Sciences this month.

Abstract
In order to examine the origin of the abrupt change in the temperature dependence of 2H NMR longitudinal relaxation times observed previously for methyl groups of L69 in the hydrophobic core of villin headpiece protein at around 90 K (Vugmeyster et...
Meteoric rise: NMR reflections
Solid-state NMR spectroscopy and other techniques have been used to make an inventory of the insoluble organic molecules found in the Sutter's Mill meteorite that may reflect the chemical resources available to the early Earth. Details of the NMR and gas chromatography-mass spectrometric analyses released upon hydrothermal treatment of a sample from the meteorite are reported in the journal Proceedings of the National Academy of Sciences this month.
