Electronic spectra of asym-triazinyl groups
The induction, resonance, and Hammett constants of 3-, 5-, and 6-asym-triazinyl groups were calculated from the data of /sup 1/H, /sup 13/C, /sup 19/F NMR spectra of isomeric aminophenyl-, hydroxyphenyl-, phenyl, and fluorophenyl-asym-triazines. The /sup 1/H and /sup 19/F NMR spectra of the solutions in dry DMSO under argon (in a concentration of 0.5 mole/liter) were recorded on a Varian A spectrometer at frequencies of 60 and 56.4 MHz, respectively; a /sup 13/C- DMSO satellite and C/sub 6/F/sub 6/ were used as internal standards. The /sup 13/C NMR spectra were recorded in a pulse regime on a Bruker HX-90 spectrometer at the frequency of 22.63 MHz, using TMS as internal standard. DMSO-D/sub 6/ (5%) was added to stabilize the resonance conditions.
