400). 700). At present the only infrared spectrum published is for the 4,s ,6-trimethy11,2,3-triazine (le) (S), and the following absorption bands are reported: 30C0, 1548, 1433, 1399, 1386, 1366, 1241, 1137, 1102, 1033, 9 9 1 , 8 9 8 , 769, and 668 cm-' . NMR spectra have been published for only a few 1,2,3-triazines. 927 (4). 257 (6). The mass spectra of most known 1,2,3-triazines(1) have been reported. From the given data it follows that a fragmentation into nitrogen, a nitrile, and an acetylene (4) occurs.
