Abstract

fetched live from OpenAlex

Abstract The pressure dependences of the peaks observed in the micro‐Raman spectra of Prussian blue (Fe 4 [Fe(CN) 6 ] 3 ), potassium ferricyanide (K 3 [Fe(CN) 6 ]), and sodium nitroprusside (Na 2 [Fe(CN) 5 (NO)]·2H 2 O) have been measured up to 5.0 GPa. The vibrational modes of Prussian blue appearing at 201 and 365 cm −1 show negative dν/d P values and Grüneisen parameters and are assigned to the transverse bending modes of the FeCNFe linkage which can contribute to a negative thermal expansion behavior. A phase transition occurring between 2.0 and 2.8 GPa in potassium ferricyanide is shown by changes in the spectral region 150–700 cm −1 . In the spectra of the nitroprusside ion, there are strong interactions between the FeN stretching mode and the FeNO bending and the axial CN stretching modes. The pressure dependence of the NO stretching vibration is positive, 5.6 cm −1 GPa −1 , in contrast to the negative behavior in the iron(II)‐ meso ‐tetraphenyl porphyrinate complex.

Full frame distilled prediction

Teacher imitation

Not 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.
