(1) The influences of adding S.O.M. on RRS intensity are as follow:
Due to there is hydroxyl group (-OH) in all the alcohols, and they can form intermolecular hydrogen bond with MB-Hb system which results in the aggregation of them . The adding of these straight chain alcohols result in enhancing of RRS with different degrees except methanol. It is obvious that the size of the alcohol is a main factor.

(4) When the cyclohexane was added, its influence was slight. It may be that there is not the hydroxyl group (-OH) and can not form intermolecular hydrogen bond with MB-Hb system in the cyclohexane. So, this phenomenon also indicated that the intermolecular hydrogen bond was important for resonance enhancement.

(1) The influences of S.O.M. addition to RRS intensity are as following:
Due to the hydroxyl group (-OH) in all the linear alcohols except methanol, they form  large polymer via combination with MB-Hb system through intermolecular hydrogen bond, which results in different increase on RRS intensity. Therefore, the size of the alcohol molecule obviously affect RRS intensity in the system.
