+description: Predict solid-state 19F NMR chemical shifts from a CIF crystal structure using the NMRNet organic-crystal model. Outputs per-atom shift values (ppm) and a simulated spectrum PNG.
+---
+
+# 19F Solid-State NMR Simulation Skill
+
+## When to use this
+Use this skill when the user provides a **CIF crystal structure file** and wants:
+- Per-atom **19F solid-state NMR** chemical shifts (ppm)
+- A simulated **19F solid-state NMR spectrum PNG**
+- A quick deep-learning based prediction using NMRNet's organic-crystal model
+
+## Inputs
+- **CIF file path** (required)
+
+## Outputs
+- `/tmp/chemclaw/ssnmr_19F_<cif_stem>.png`
+- `/tmp/chemclaw/ssnmr_19F_<cif_stem>.md`
+
+## Shared assets
+- Required shared paths:
+  - `../nmr-prediction/assets/NMRNet`
+  - `../nmr-prediction/assets/Uni-Core`
+
+## Environment setup
+
+### 1. Install Uni-Core once
+```bash
+cd nmr-prediction/assets/Uni-Core
+python setup.py install
+```
+
+### 2. Install Python dependencies
+```bash
+cd f-nmr-simulation
+pip install -r requirements.txt
+# 如果还没装 torch：pip install torch  (CPU 版即可)
+```
+
+### 3. Download 19F solid-state weights
+```bash
+cd f-nmr-simulation
+python f_nmr_simulation.py --setup
+```
+
+下载目标：
+- `weights/finetune/solid/Organic Crystal/F_.../cv_seed_42_fold_0/checkpoint_best.pt`
+- `weights/finetune/solid/Organic Crystal/F_.../target_scaler.ss`
+
+## How to run
+
+```bash
+cd f-nmr-simulation
+python f_nmr_simulation.py path/to/structure.cif
+```
+
+## Notes
+- This is a **solid-state** NMR skill, not liquid-phase SMILES prediction.
+- Input should be a crystal structure file (`.cif`), not a SMILES string.
+- The script is self-contained and only reuses NMRNet / Uni-Core assets.
