我们测量了77 - 400 K温度范围内两种氮同位素（-和-）在金刚石中氮空位（N-）中心基态的电子和核自旋跃迁频率。测量使用拉姆齐干涉法和直接光学读出的核和电子自旋。我们提取耦合参数（-），和，和它们的温度依赖性的两种同位素。在室温附近自旋流形内的核自旋跃迁的温度依赖性为0.52（1）ppm/K（|mI=-1参与者|（1）、（1）、（2）、（3）、（4）、（5）、（|mI=−1/2 π参与|mI=+1/2 Ω）。零场分裂参数在-和-之间的同位素位移为kHz。剩余横向磁场被观察到移动的核自旋跃迁频率，特别是对-。我们已经精确地确定了一组相关的参数，用于开发对环境因素的敏感性大大降低的基于核自旋的金刚石量子传感器。
We measure electron- and nuclear-spin transition frequencies in the ground state of nitrogen-vacancy (N-) centers in diamond for two nitrogen isotopes (-and-) over temperatures ranging from 77 to 400 K. Measurements are performed using Ramsey interferometry and direct optical readout of the nuclear and electron spins. We extract coupling parameters(for-),,,, and, and their temperature dependences for both isotopes. The temperature dependences of the nuclear-spin transitions within thespin manifold near room temperature are found to be 0.52(1) ppm/K for-(|mI=−1⟩↔|mI=+1⟩) andppm/K for-(|mI=−1/2⟩↔|mI=+1/2⟩). An isotopic shift in the zero-field splitting parameterbetween-and-is measured to bekHz. Residual transverse magnetic fields are observed to shift the nuclear-spin transition frequencies, especially for-. We have precisely determined the set of parameters relevant for the development of nuclear-spin-based diamond quantum sensors with greatly reduced sensitivity to environmental factors.
