Solid-state NMR spectra were recorded on a Bruker
Avance II spectrometer (Bruker Biospin, Faellanden, CH) operating
at 700 MHz ¹H Larmor frequency (16.4 T), corresponding
to 146 MHz ¹³C Larmor frequency. The spectrometer is equipped
with a 3.2 BVT MAS probehead in double-resonance mode. The spinning
rate was regulated to 11111 ± 2 Hz using dry air, and the temperature
was set to 280 K. The pulse lengths were 2.5 and 3.5 μs for ¹H and ¹³C, respectively. Cross-polarization^{20 (link)} was achieved by matching the k = 1 Hartmann–Hahn condition.^{21 (link)} For the {¹H}¹³C HETCOR spectra, the spectral
windows for the different nuclei were 60 and 315 ppm for ¹H and ¹³C, respectively. During the ¹H magnetization
evolution under the chemical shift in the indirect dimension of heteronuclear
correlation experiments, a PMLG decoupling sequence was used to suppress ¹H–¹H dipolar couplings.^{22 (link),23 (link)} The CP spectrum was denoised through the MCR procedure.^{24 (link),25 (link)}

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
