To query experimental molecular spectra—such as Infrared (IR), Mass Spectrometry, and UV-Vis—from standard experimental databases like the NIST Chemistry WebBook for baseline comparison against properties computed via MLIPs or DFT.
Use the query_spectra.py script to fetch available spectrographic data for a given chemical formula. The script automatically searches the NIST Chemistry WebBook, resolves the compound, and downloads all available JCAMP-DX (.jdx) formatted spectra into the specified directory.

# chem-db-spectra
## Goal
To query experimental molecular spectra—such as Infrared (IR), Mass Spectrometry, and UV-Vis—from standard experimental databases like the NIST Chemistry WebBook for baseline comparison against properties computed via MLIPs or DFT.
## Instructions
### Step 1. Query Spectra Data
Use the `query_spectra.py` script to fetch available spectrographic data for a given chemical formula. The script automatically searches the NIST Chemistry WebBook, resolves the compound, and downloads all available JCAMP-DX (`.jdx`) formatted spectra into the specified directory.
```bash
# Env: base-agent
python .agents/skills/chem-db-spectra/scripts/query_spectra.py <formula> <output_dir> [--type {IR,Mass,UVVis,All}]
```
Parameters:
- `formula`: The chemical formula to query (e.g., `CH4`, `C2H6O`).
- `output_dir`: The directory path to save the downloaded JCAMP-DX (`.jdx`) spectrum files.
- `--type`: Filter the spectrum type to download (options: `IR`, `Mass`, `UVVis`, `All`). Default is `All`.
## Constraints
- **Environments**: The scripts require the `base-agent` Conda environment.
- **Spectrum Format**: Output data is universally saved in JCAMP-DX (`.jdx`) standard format. You must use appropriate spectroscopic python package (e.g., `jcamp`) if you need to parse it back into numpy arrays.
- **Scraping Dependability**: This script utilizes HTML scraping (`beautifulsoup4`). If the NIST WebBook layout changes in the future, the selectors may need to be updated.
