Abstract

Section titled ā€œAbstractā€

Abstract The adjusted Carr-Purcell-Meiboom-Gill (CPMG) sequence is mathematically simulated to obtain the 13 C nuclear spin signals coupled to a negatively-charged nitrogen-vacancy (NV āˆ’ ) center in diamond. The pulse interval ratio and scanning frequency of the sequence were precisely adjusted to achieve the high-resolution 13 C nuclear spin detection. The frequency resolution of the sequence was 5.8 times improved than that of the original CPMG sequence, and the full width at half maximum of the coherence dips were less than 1.7 kHz. The adjusted method can be extended to other dynamical decoupling sequence, and offers a promising approach to improve identification of the nuclear spins in coupled electron-nuclear spin systems.
