Atta-ur-Rahmanion the commitment to a major reform had been intensified by what the Conservatives regarded as an unnecessary capitulation to trade union power in 1969 when Barbara Castle’s ‘.’. proposals proved to be abortive. This followed the spectre of a revolt by back bench Labour MPs, supported by several me

,Spin—Spin Coupling in 1-NMR Spectroscopy, may be split into doublets, triplets, quartets, or multiplets. Thus ethyl chloride (Figure 2.1) would afford a triplet for the methyl group and a quartet for the methylene protons. This splitting occurs because nonequivalent protons attached to the same carbon or to adjacent carbon atoms exhibit sp

,Chemical Shifts and Spin—Spin Couplings in 13C-NMR Spectroscopy,easured with reference to TMS taken as zero, although addition of TMS is often not carried out since the position of the solvent signal with reference to TMS is known, and the signals may be calibrated with reference to the solvent signal. The chemical shifts of common solvents are presented in Tabl
