| Abstract: | | 1. |
Nitroxyl biradicals of the triazine, N,N -bis(triazinyl)ethylenediamine, N,N-bis(triazinyl)piperazine, and s-nitropyrimidine series have been prepared.
| | 2. |
The ESR spectra of liquid and frozen solutions of these biradicals have been obtained and N. - O group separations calculated.
| | 3. |
Toluene solutions of (II), (V), (VI), and (X) biradicals contain at least four different conformations, each with its own value of the exchange integral.
| | 4. |
In one of the biradical (V) conformations, spin interaction exchange is through the chain of atoms linking the N.-O fragments.
