Indirect NMR detection via proton of nuclei subject to large anisotropic interactions, such as 14N, 195Pt, and 35Cl, using the T-HMQC sequence

Racha Bayzou et al.

Summary: Recently, the T-hetero-nuclear multiple quantum coherence (T-HMQC) sequence using the TRAPDOR recoupling has been introduced for the indirect detection of quadrupolar nuclei via protons in solids. The sequence is simple and has low noise, making it applicable for detecting nuclei subject to large chemical shift anisotropy. The study also presents a proton detection method for double-quantum coherences of N-14 nuclei using this sequence. The article derives the Hamiltonian describing the spin dynamics during the TRAPDOR recoupling and analyzes the factors affecting the efficiency of the T-HMQC sequence.

Monitoring of Cocrystal Dissociation during the Wet Granulation Process in the Presence of Disintegrants by Using Low-Frequency Raman Spectroscopy

Naoto Suzuki et al.

Summary: This study aimed to evaluate the effect of different coformers and disintegrants on the dissociation behavior of cocrystals during wet granulation process. The results showed that the dissociation rate of cocrystals varied depending on the types of coformers and disintegrants, indicating their impact on the relative stability of cocrystals during wet granulation.
