Inert, non-flammable lubricating oil . Inert, non-flammable lubricating oil . Polymer is a blend of
oligomers . Also used as an ultraviscous solvent for ¹H NMR spectroscopy to better identify individual
components in a complex mixture . The ultraviscous polymer solvent (mixed as 80% Halocarbon
/20% CDCl 3 ) greatly reduces the molecular tumbling of small molecules, thereby making
the nuclear Overhauser effect (NOE) very large and of negative sign . In a NOESY experiment, the
spectrum of the target molecule can be cleanly extracted from the mixture .
