Experimental aspects of ¹⁴N overtone RESPDOR solid-state NMR spectroscopy under MAS beyond 60 kHz.

ABSTRACT: Nitrogen-14 (¹⁴N) overtone (OT) spectroscopy under fast magic angle spinning (MAS) conditions (>60 kHz) has emerged as a powerful technique for observing correlations and distances between ¹⁴N and ¹H, owing to the absence of the first-order quadrupolar broadenings. In addition, ¹⁴N^OT allows selective manipulation of ¹⁴N nuclei for each site. Despite extensive theoretical and experimental studies, the spin dynamics of ¹⁴N^OT remains under debate. In this study, we conducted experimental investigations to assess the spin dynamics of ¹⁴N^OT using the rotational-echo saturation-pulse double-resonance (RESPDOR) sequence, which monitors population transfer induced by a¹⁴N^OT
