A proposal is given to use the ##IMG## [http://ej.iop.org/images/0953-4075/53/13/135401/bab894bieqn1.gif] {${X}^{1}{\Sigma}\left(v,J,F\right)=\left(0,0,1/2\right)-\left(0,1,1/2\right)$} transition of the HeH + (2.0 THz), NeH + (1.0 THz), and ArH + (0.62 THz) molecular ions as novel frequency standards in the terahertz region. This transition is free from the electric-quadrupole shift, and the DC Stark and Zeeman shifts are much less than those of the CaH + and MgH + molecular ions. These transitions are useful for locking the frequencies of oscillators like quantum cascade lasers (QCL) or resonant tunnel diodes (RTD) with uncertainties of 10 −15 .

太赫兹频率标准的稀有氢离子的前景

提出了使用## IMG ##的建议[http://ej.iop.org/images/0953-4075/53/13/135401/bab894bieqn1.gif] {$ {X} ^ {1} {\ Sigma} \ left(v,J,F \ right)= \ left(0,0,1 / 2 \ right)-\ left(0,1,1 / 2 \ right)$} HeH +(2.0 THz),NeH +(1.0 THz)和ArH +(0.62 THz)分子离子作为太赫兹区域的新型频率标准。该跃迁没有四极电位移,并且DC Stark和Zeeman位移远小于CaH +和MgH +分子离子的位移。这些过渡对于锁定诸如不确定性为10 -15的量子级联激光器(QCL)或谐振隧道二极管(RTD)之类的振荡器的频率很有用。
