It is therefore relatively easy to identify the aldehyde group (together with the C=O stretching at about 1700 cm-1) since essentially no other absorptions occur at these wavenumbers (see the example of the IR spectrum of butanal in Figure 6.4d). The stretching vibration of triple bonds C≡C and C≡N have absorption bands of about 2100–2200 ... Normally, O-doped g-C 3 N 4 shows a weak peak at 1010 cm-1 which is ascribed to the C–O stretching vibration [21, 40, 41]. However, for the x-OCN samples, this peak is very weak.

IR Spectroscopy Tutorial: Amines. The N–H stretches of amines are in the region 3300-3000 cm -1. These bands are weaker and sharper than those of the alcohol O–H stretches which appear in the same region. In primary amines (RNH 2 ), there are two bands in this region, the asymmetrical N–H stretch and the symmetrical N–H stretch.

The intensity of the peaks corresponding to the amide II band and the -C=O stretching vibration has significantly decreased, indicating carbamate bond chain breakup. Furthermore, the intensity of the N H stretching vibration peak at 3300–3400 cm −1 increases dramatically, showing carbamate bond breakdown and the formation of …Industrial dye effluent causes significant risks to the environment.
