Abstract
It was observed that Dimethoate {O, O-dimethyl-S- (N-methylcarbamoylmethyl) -pithiophosphate}, one of the organo-phosphoric insecticides, shows two absorptions at 3460 and 3430 cm-1, being assigned to NH stretching vibration of free molecule in dilute carbon tetrachloride solution. Changes of absorption intensity in various concentrations and of the absorption bands measured in a solvent mixture of both carbon tetrachloride and mesitylene were examined. In this connection, N-methylphenylmercaptoacetamide and N-methyl-β-phenylpropionamide, as related compounds, were also synthesized and their NH stretching vibrations in carbon tetrachloride were examined. The absorption3460 cm-1 is considered to be due completely to the free NH group, and that at 3430 cm-1 has been clarified to be caused by the stretching vibration fo the NH-group, intramolecular hydrogen bonding being formed such like N-H…S.
