UV-Vis Spectroscopy / Imaging (electronic absorption) L1-145
Unclaimed Principle — open for contribution
This Principle is declared in the catalog but has no reference solver, no pinned dataset, and is not registered on-chain. There is no reward pool. Submitting a cert against this Principle today will record the cert for reproducibility but pay zero PWM.
To claim it as a Bounty #7 contribution: open a PR adding (1) a reference solver, (2) ≥1 dataset pinned to IPFS, (3) updates to the L3 manifest with dataset CIDs. After verifier-agent triple-review, the founders' 3-of-5 multisig signs PWMRegistry.register() and the Principle becomes mineable.
Forward model E
Broadband UV-Vis light (200-800 nm) passes through sample; absorption by electronic transitions (pi->pi*, n->pi*, d-d, MLCT) follows Beer-Lambert A = epsilon(lambda) * c * l. Cuvette / fiber-based spectrometry or hyperspectral imaging via monochromator + camera.
