The infrared spectra of some chlorinated derivatives of s-triazine

“…1(A)] shows two characteristic peaks at 3334 and 3205 cm −1 , respectively. The former can be attributed to the NH stretching of the free amino group, and the latter can be assigned to the NH stretching of the hydrogen‐bonded amino group; this is in good agreement with the literature data 30, 31. In ACHT [Fig.…”

“…Similar results were obtained in the infrared study of other chlorinated s ‐triazine derivatives, and Heckle et al31 believed that the behavior of this ring band resulted from a mass effect associated with the relatively heavy chlorine atoms corresponding to differing degrees of chlorination, which agreed well with this finding. Another band worth mentioning in ADCT is the 850‐cm −1 peak, which is a characteristic band of triazine derivatives containing two or three chlorine atoms bonded directly to ring carbon atoms 31. As expected, in ACHT, because of the presence of only one chlorine atom in the structure, the 850‐cm −1 band disappears.…”

“…This difference can be readily identified by an FTIR study, as shown in Figure 1. The infrared spectra of ADCT and other chlorinated derivatives of s ‐triazine have been extensively studied 30, 31. ADCT [Fig.…”

“…In the region of 1600–1900 cm −1 , ADCT shows three sharp peaks at 1732, 1690, and 1650 cm −1 . These peaks are believed to be caused by the planar triazine ring stretching vibrations 30–32. The 1650‐cm −1 band and 1732‐cm −1 band are little affected by the presence of one chlorine atom bonded to the triazine ring in ACHT.…”

“…Even with these problems in mind, the resulting spectrum strongly suggests the presence of etheral, hydroxy-, and chlorotriazine derivatives. It has been reported that 2,4,6-substituted triazines exhibit bands in the 800-cm"1 region due to an out-of-plane ring vibration (21, 23). The absolute frequency of the vibration is strongly dependent upon the types of substituents present on the triazine ring.…”
