Abstract:
In a previous work the existence of an hydrogen bond between the difluoromonochloromethane (R 22) and the diethylesters of alpha-omega dicarboxylic acids was pointed out. In the present paper, the influence on absorption of substituents for the hydrogen of the CH2 has been studied in a single compound (diethylmalonate). The results show that electron acceptor substituents obstruct the forming of the hydrogen bond while electron donor substituents improve it.

The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
