溶液中钒氧离子的ESR谱具有一个有趣的特征，即各个超精细组分的线宽依赖于核自旋取向mI。我们确定了这种效应的起源是H. M. McConnell，即VO++离子的“微晶”的存在，它引起g张量和超精细相互作用的各向异性。本文将在9.25kMc和24.3kMc下的线宽测量结果与D. Kivelson，我们能够得出微晶模型的有效性。
The ESR spectrum of vanadyl ion in solutions has the interesting feature that the linewidths of the individual hyperfine components depend on the nuclear spin orientation, mI. We have determined that the origin of the effect is the mechanism proposed by H. M. McConnell, namely, the existence of a ``microcrystal' about the VO++ ion which gives rise to anisotropies in the g tensor and hyperfine interaction. By comparing the results of linewidth measurements made at 9.25 kMc and at 24.3 kMc with the results of calculations made by D. Kivelson, we were able to conclude the validity of the microcrystallite model.
