A long-overdue hypothesis on the origin of the magnetic field of Jovian planets is presented. It is proposed that rapid parahydrogen ↔ orthohydrogen exchange catalyzed by aerosol clouds of parahydrogen-rich planetary layers renders a hyperpolarized nuclear spin state of orthohydrogen (and potentially other proton-containing compounds). This enhancement of nuclear spin polarization by several orders of magnitude (termed hyperpolarization) significantly enhances otherwise negligible proton magnetization. It is hypothesized that this persistent exchange process produces planetary magnetism on Jovian planets. This hypothesis builds on recent experimental evidence that parahydrogen exchange may indeed produce hyperpolarized orthohydrogen.

副氢诱导的木星行星磁化?

提出了一个迟来的关于木星行星磁场起源的假设。有人提出,由富含仲氢的行星层的气溶胶云催化的快速仲氢 ↔ 正氢交换呈现正氢(以及其他潜在的含质子化合物)的超极化核自旋状态。这种核自旋极化增强了几个数量级(称为超极化)显着增强了原本可以忽略不计的质子磁化。据推测,这种持续的交换过程会在木星行星上产生行星磁性。这一假设建立在最近的实验证据之上,即副氢交换确实可能产生超极化的正氢。
