Practical Aspects of Modern Routine Solid-State Multinuclear Magnetic Resonance Spectroscopy: One-Dimensional Experiments
Bibliographic record
Abstract
New solid-state NMR (SSNMR) methods and applications continue to blossom such that a diverse array of physical, chemical, and biological problems are now being addressed using a variety of SSNMR experiments. While SSNMR is far from routine for chemists in the manner that a technique such as solution NMR is, there are nevertheless numerous applications of SSNMR which would be beneficial to many “non-specialists”, e.g., synthetic chemists seeking to characterize their materials. This article gathers together practical details for those one-dimensional experiments which, in a broad sense, are considered “routine ” in a modern SSNMR laboratory. Emphasis is placed on providing information and over 300 key references in a manner which will be useful for the novice and the non-specialist. For practicing SSNMR spectroscopists, it is hoped that this article will serve as a valuable reference in the laboratory. In addition to providing a brief review of pulsed Fourier transform NMR, the article discusses experimental details relating to the study of solid samples containing spin- 1 2 nuclei, non-integer quadrupolar nuclei, and deuterium.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
