✦ Synopsis

The mass spectra of the C, to C, n-alkanals and a number of branched aldehydes have been obtained at a resolution sufficient to resolve the O-CH4 doublets. From the resolved spectra, a study of metastable transitions, and the spectrum of one deuterium-labelled alkanal, (n-hexanal-2,2-dz) the major fragmentation reactions have been elucidated. Of particular interest are the y-cleavage reaction, leading to [C,H,O]+ in the n-alkanals, which proceeds both by a simple cleavage and by cleavage preceded by hydrogen interchange, and the loss of CzH4, which involves loss of the C, and, probably Cs, carbons.

An inductively coupled plasma mass spectrometer (ICP-MS) system is described in which the quadrupole mass filter can be operated conventionally or in the 'second' stability region (with Mathieu parameters q=7.547, a=0.0295). With operation in the second region a resolution at half-height (Rw) of up
