Investigation of amino acetonitrile (NH<sub>2</sub>CH<sub>2</sub>CN) — a precursor of glycine, in the interstellar medium
Bibliographic record
Abstract
Known values of rotational and centrifugal distortion constants, in conjunction with electric dipole moment, have been used to calculate energies for the ground rotational levels, ground vibrational state, and ground electronic state of amino acetonitrile (NH 2 CH 2 CN), which is of interest for studies of life in the universe. Probabilities for radiative transitions between the rotational levels are also calculated. Such transition probabilities are used in conjunction with scaled values for the collisional rate coefficients for large velocity gradient calculations. A line 1 10 –1 11 at 450.31 MHz is found to show anomalous absorption. Two observed lines 9 09 –8 08 at 80.947 GHz and 12 0,12 –11 0,11 at 107.283 GHz, and another nine lines, 9 18 –8 17 , 7 16 –6 15 , 8 17 –7 16 , 9 19 –8 18 , 10 19 –9 18 , 8 08 –7 07 , 10 0,10 –9 09 , 11 0,11 –10 0,10 , and 7 07 –6 06 , are found to show emission features. There are several other observed lines, which are found weaker than these 11 lines. These 10 additional lines may help in the identification of amino acetonitrile in the interstellar medium.

How this classification was reachedexpand
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.
