  1. 1.

    The paramagnetic derivatives of diethylenimino-S-triazine, pentaethyleniminocyclotriphospha-zatriene, and p-N-di-(β-chloroethyl)aminophenylacetic acid were synthesized.

  2. 2.

    The 4-aminomethyl- and 4-(β-aminoethyl)-2, 2, 6,6-tetramethylpiperidine-1-oxyls were synthesized.

  3. 3.

    A study was made of the reaction of the new spin-labeled compounds with DNA, synthetic polynucleotides, and albumin.

  4. 4.

    A study was made of the τsec of the spin-labeled polynucleotides as a function of the action of deoxyribonuclease, temperature, and the formation of purine-pyrimidine complexes.

  5. 5.

    The paramagnetic ethers of cellulose were obtained by the condensation of alkali cellulose with the paramagnetic derivatives of dichloro- and diethyleniminotriazine, and also of pentaethyleniminocyclo-triphosphazatriene.
