To increase the SNR in earth's magnetic field NMR the
macroscopic spin order of parahydrogen can be used to
produce hyperpolarization. Therefore after an
unsaturated substrate is hydrogenated with parahydrogen
field cycling has to be applied. Here, we show that a
preparation field in the regime of mT switched on for
several seconds enables the transfer of PHIP-generated
hyperpolarization from parahydrogen to
19
F
and that this process is field dependent. For the
measurement a self built coil based earth field
spectrometer was used.
