我们估计了O-16(2)+分子离子跃迁频率的Stark和Zeeman位移，以此作为寻找质子与电子质量比µ变化的一个步骤。O-16(2)+分子离子的X-2pInu=21-a(4)pIv=0或X-2pIv=21-a(4)pIv=1跃迁频率(太赫兹区域)对u的变化特别敏感。还要注意的是，O-16(2)+跃迁频率的斯塔克位移预计会比异核双原子分子的斯塔克位移小得多。然而，O-16(2)+跃迁频率的实际系统不确定度从未被估计过。我们估算了不同O-16(2)+跃迁频率下的斯塔克和塞曼位移。当串状晶体中的分子离子形成线性陷阱(陷阱电场)时
We estimate the Stark and Zeeman shifts in the transition frequencies of the O-16(2)+ molecular ion as a step in the search for the variation in the proton-to-electron mass ratio mu. The X-2 Pi nu = 21- a(4)Pi v = 0 or the X-2 Pi v = 21- a(4)Pi v = 1 transition frequencies (THz region) of the O-16(2)+ molecular ion have particularly high sensitivity to the variation in mu. Note also that the Stark shift in the O-16(2)+ transition frequencies is expected to be much smaller than that for heteronuclear diatomic molecules. However, the actual systematic uncertainties for the O-16(2)+ transition frequencies have never been estimated. We estimated the Stark and Zeeman shifts in the different O-16(2)+ transition frequencies. When the molecular ions in a string crystal formed in a linear trap (trap electric field
