## Abstract 2‐Hydroxy‐5‐methylbenzophenone (E) and (Z) oximes and 5,8‐diethyl‐7‐hydroxy‐6‐dodecanone (E) and (Z) oximes have been treated with N,O‐bis(trimethylsilyl)acetamide (BSA) to give di‐(trimethylsilyl) derivatives. The GLC data and the combined GC‐MS analysis of derivatized oximes are prese

✦ Synopsis
The crystal structure of norpropoxyphene maleate is presented. The conformation is discussed in relation to similar compounds. A gas chromatographic-mass spectrometric investigation indicates that earlier proposed metabolites may be formed during the gas chromatographic separation.

A novel algorithm is described for the improved estimation of isotopomer ratios from gas chromatographic/mass spectrometric data. The minor isotopomer peak proÐle is Ðtted to an admixture of the major proÐle and its Ðrst and second derivatives. By this means allowance is made for non-coincidence in
