Therefore, these preliminary results have advantages in developing new and high efficiency carboxylic acid amide fungicides.

Careful examination of the spectra shows that during heating of the samples under study many amide bands become weaker in intensity and broader in profile and their positions shift first up and then down.

The transfer of free electron to the conduction band of oxide groups (carboxylic and amide), in the functionalized CNTs changing the hole concentration.

IR (KBr, [cm.sup.-1]): 3362 (NH), 1742, 1690 (COOH), 1618 (amide I), 1526 (amide II).

Synthesis of Fatty Amides from Crude Rice Bran Oil.

In summary, the infrared spectra collected in this study suggest that interactions occur between 2-pyrrolidone and [C.sub.60] resulting from possible donation of the electron pairs from the oxygen part of its amide functionality into the anti-bonding MO's of the [C.sub.60] At lower concentrations of 2-pyrrolidone (5 and 2 [micro]L of 2-pyrrolidone per mL of toluene and toluene saturated with [C.sub.60]), a significant shift of its amide carbonyl absorption (~1700 [cm.sup.-1] to ~1687 [cm.sup.-1]) is observed supporting this kind of interaction.

The Gaussian curve fitting analysis of the amide I band peak was carried out based on the preliminary study of Meng-Xia and Yuan (2002), showed characteristic peaks at 1,611 to 1,639 [cm.sup.-1] that were attributed to [beta]-sheets.

The composite backbone amide resonance of endogenous mobile proteins is around 8.3 ppm in the proton nuclear MR spectrum (which is 3.5 ppm downfield from water).

The bands in the amide I region provide insight into the protein secondary structure.

[sup.13]C NMR spectrum also supported the presence of amide group from the deshielding value of carbon attached to -CONH group at [delta] 169.3 ppm and carbonyl group (part of a five member ring) at [delta] 169.47 ppm.
