<i>In situ</i> micro Raman investigation of electrochemically formed halide and pseudohalide films on mercury electrodes
Bibliographic record
Abstract
Abstract Oxidation of pure mercury electrodes was followed by in situ surface‐unenhanced Raman spectroscopy. A special spectroelectrochemical cell allowed the observation of spectral features of the oxidation products using a Raman microprobe. The electrochemical behaviour of mercury in basic solution, halide (F − , Cl − , Br − and I − ) and pseudohalide (SCN − ) media was investigated. Insoluble films were formed during the anodic processes in all these systems. The identities of the electrochemically generated films were clearly determined from the Raman spectra. The main product of the electrochemical oxidation of mercury in basic solutions was solid HgO. The anodic behaviour of mercury in the presence of halide yielded insoluble Hg 2 X 2 compounds (where X is the halide). The time dependence of the Raman signals indicated a diffusion‐controlled growth of the halide films. The oxidation of mercury in SCN − solutions also produced a solid precipitate [Hg 2 (SCN) 2 ]. Raman bands due to soluble mercury(II) thiocyanate complexes [Hg(SCN) x 2− x ], present in the electrochemical diffusion layer, were also observed. Copyright © 2002 John Wiley & Sons, Ltd.

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.
