The separation of gaseous hydrocarbon isomers by thermal diffusion has been demonstrated. Experiments were made in a Clusius column and mixtures analyzed by a mass spectrometer. Binary mixtures of ...

Chemical ionization mass spectrometers accurately evaluate VOCs in a wide range of environments. The analysis becomes ambiguous when a compound is obscured by either isomeric or isobaric interference.

All symmetrical molecules with non-zero nuclear spin exist in nature as nuclear-spin isomers (NSIs). However, owing to the lack of experimental information, knowledge is rare about interconversions of ...
