Abstract
Room temperature EPR signals in special blends of tobacco widespread in middleeast have been observed. Two characteristic signals have determined. A large broad signal characteristic of manganese is found to be indicative of the quality of the tobacco brand. An additional superimposed narrow signal have been found to be very stable and increase with temperature This sharp signal of approximately 5 gauss, characteristic of small organic radicals is very stable and its magnitude increase drastically with temperature. A variety of small hyperfine coupling signals have been observed during a controlled temperature dependent EPR experiment.
