✦ Synopsis
The ions at m/z 75 [HC (OCH 3 ) 2 ] and m/z 89 [CH 3 C (OCH 3 ) 2 ] decompose into the ion at m/z 47 and into the ions at m/z 43 and 47, respectively. These precursor ions are prepared by the loss of hydrogen (H) from the central carbon in ionized dimethoxymethane (1) and 1,1-dimethoxyethane (2). The m/z 47 ions, which are common to both compounds, are generated by the transfer of a hydrogen atom and a methyl group to the ether oxygen followed by the loss of CO and CH 2 CO, respectively.
