许多质量，特别是不稳定原子核的质量，是通过确定最有效地耦合被捕获离子的三个运动中的两个的驱动力的频率，用潘宁陷阱中的离子来测量的。与简单的估计相反，对这种边带质谱法为何起作用的缺失解释始于已建立的布朗-加布里埃尔不变定理。
Many masses, particularly the masses of unstable nuclei, are measured with ions in Penning traps by determining the frequency of a driving force that most efficiently couples two of the three motions of trapped ions. A missing explanation of why such sideband mass spectroscopy works, contrary to simple estimates, begins with the established Brown-Gabrielse invariance theorem.
