“…This leads to increase the energy of -MO'S. In addition, it was found that the tertiary N-atom is more basic than NH 2 or NH groups in the pyridine moiety ring [ 39]. Thus, the tertiary N-atom get protonated first taking into consideration the protonation of N atoms of the pyridine moiety is that the same.…”

“…Factor analysis. The data from each set of five spectra taken at the different excitation wavelengths, for each individual fish (a total of 60 spectra) were treated utilizing the self‐modeling factor analysis method (21) using a locally written (22) program which has proven (23–26) itself capable of separating strongly overlapping spectra, as well as quite successfully removing statistical noise. The method analyzes a set of normalized (to the same area) spectra as an eigenvalue‐eigenvector problem, in which the calculated contributing spectra are derived from the eigenvectors and the corresponding eigenvalues represent the contribution of the calculated spectra to the experimental spectra.…”

The fluorescence spectra of the tropical fish, Cardinal Tetra (Paracheirodon axelrodi), originating in the Amazon region of Brazil, were determined. These spectra were then treated using factor analysis, generating two contributing spectra and separating out the noise. Time-resolved fluorescence results indicated that the fluorescent system in the epidermis undergoes excited state reaction. Excited state proton transfer is suggested as being present. Both intentionally stressed and nonstressed individuals were used and some small differences were noted in the contributions of the two calculated contributing spectra to the experimental spectra, presumably as a function of stress. The results are compared with those obtained by the standard determination of cortisol level using the whole body extraction method and it is suggested that the method could be tested as an improved, nondestructive way to determine stress in this species, which is a necessary step in the development of ''best management practices'' of methods for storage and transport of the fish.
