As can be seen in Fig. 3a, the aromatic ring protons multiplet of nAY molecule were observed from 7.11 to 8.70 ppm.
Simple hydroperoxides with two oxygen atoms per molecule were observed at relatively low temperatures above 370 K with liquid and gas present.
Bands corresponding to the twisting vibrations of the C-H bonds in the same part of the molecule were observed at 1143/1147 cm-1 in the calculated/experimental Raman spectra and at 1160/1153 cm-1 in the calculated/experimental IR spectra.
When a hydrogen atom of the molecule was substituted by Cl or Br, practically no change in the absorbed and emitted energies relative to those of the indigo molecule were observed; however, when N was substituted by S or Se, the absorbed and emitted energies increased.
Additionally, the sodium-attached and potassium-attached species of this molecule were observed with similar distribution, supporting the assignment based on accurate mass.
Interestingly, in contrast to leptin or leptin receptor-deficient rodents, in human patients, gradual compensations of several endocrine functions that were initially impaired due to a mutated leptin molecule were observed, possibly due to the longevity of humans [ 26].
