    Abstract

    An attempt was made to study the internal rotations of the methyl group in o- and m-methylpyridines, 2-methylpyrazine, 4-methylpyrimidine, 4-methylpyridadine, and 4-methyl-1,2,3-triazine. A mechanism of the rotational barrier changes by excitation and electron attachment and the relationship of the rotational barriers with the number and position of the substituted nitrogen atoms were shown.
