Kinetic isotope effects of 12 CH 3 D + OH and 13 CH 3 D + OH from 278 to 313 K
Methane is the second most important long-lived greenhouse gas and plays a central role in the chemistry of the Earth’s atmosphere. Nonetheless there are significant uncertainties in its source budget. Analysis of the isotopic composition of atmospheric methane, including the doubly substituted species CH3D, offers new insight into the methane budget as the sources and sinks have distinct isoto...

متن کاملChiral molecule formation in interstellar ice analogs: alpha-aminoethanol NH 2 CH(CH 3 )OH
Aims. Aminoalcohol molecules such as alpha-aminoethanol NH2CH(CH3)OH may be aminoacid precursors. We attempt to characterize and detect this kind of molecules which is important to establish a possible link between interstellar molecules and life as we know it on Earth. Methods. We use Fourier transform infrared (FTIR) spectroscopy and mass spectrometry to study the formation of alphaaminoethan...
متن کاملCH 3 OH abundance in low mass protostars
We present observations of methanol lines in a sample of Class 0 low mass protostars. Using a 1-D radiative transfer model, we derive the abundances in the envelopes. In two sources of the sample, the observations can only be reproduced by the model if the methanol abundance is enhanced by about two order of magnitude in the inner hot region of the envelope. Two other sources show similar jumps...
