“…Unfortunately, the residuals from the global fit are an order of magnitude higher than the experimental accuracy. Comparing the present results for the m 6 with the results of the global fits for the antisymmetric wagging and N-N stretching bands [8,9], one can say that they seem to be similar.…”

“…Table 1 from paper [9], including the calculated harmonic vibrational transitions and relative IR intensities in hydrazine for different ab initio models, turned out to be very helpful to choose the possible perturbers.…”

“…As shown by FT‐IR spectroscopy in Figure , PAA‐based microparticles show characteristic peaks of PAA and MBA as follow: 2850 and 2930 cm −1 attributed to CH 2 stretching vibrations, 1720 cm −1 ascribed to carbonyl groups of PAA and 1640 cm −1 originated from carbonyl groups of MBA . After treatment with hydrazine monohydrate, absorption peak at 1086 cm −1 is attributed to the NN stretching movements, small peak at 1316 cm −1 arises from CN stretching, strong peak at 1624 cm −1 stems from amidation of CO groups of PAA and peaks at 3180 and 3320 cm −1 are attributed to primary amines of attached hydrazine molecules . To create a covalent acid‐labile bond (NC) between drug and polymer, TFA was used as a catalyst in methanol as a polar solvent.…”

“…There is a disappearance of peak at 906 cm −1 in Figure (c) which suggests the opening of the epoxide ring by hydrazine treatment. The presence of peak at 1060 cm −1 comes from NN stretching of introduced hydrazine moiety . However, after metal deposition [Figure (d)], peaks are not very sharp as shown in Figure (c).…”
