Hyperpolarized (HP) propane is a promising contrast agent for magnetic resonance imaging
(MRI) of lungs and for studying porous media. The parahydrogen-induced polarization …

Abstract A new Nuclear Magnetic Resonance (NMR) pulse sequence is proposed for
manipulating ParaHydrogen Induced Polarization (PHIP) at high magnetic fields. The …

The site-specific signal enhancement provided by parahydrogen induced polarization
(PHIP) may be combined with magnetic resonance imaging (MRI) to study chemical and …

DOSY is a powerful spectroscopic NMR technique that resolves components in mixtures
through the evaluation of different diffusion coefficients. The application of DOSY to dilute …

In the gas phase we have a well-defined homogeneous physical system, and the theory for
dilute gas behavior is in an advanced stage. In dilute gases, we can expand the molecular …

Parahydrogen induced polarization (PHIP) is a powerful hyperpolarization technique.
However, as the signal created has an anti-phase characteristic, it is subject to signal …

The antiphase character of the PHIP associated signals after a hydrogenation reaction is
particularly sensitive to line broadening introduced by magnetic field inhomogeneities and …

Despite the large degree of polarization in PHIP experiments compared to the Boltzmann
factor, the presence of a large amount of non-reacted molecules with thermal polarization is …

A new pulse sequence aimed to filter out NMR signals coming from thermally polarized
protons in PHIP experiments based on the OPSY pulse sequence (Only Parahydrogen …

We demonstrate that the relative phases in the refocusing pulses of multipulse sequences
can compensate for pulse errors and off-resonant effects, which are commonly encountered …
