In view of the biological production of trimethylstibine ((CH 3 ) 3 Sb) in the natural environment, the fate of this species when exposed to ambient oxygen has been studied. The results obtained show that the oxidation process leads to a complex series of products. Trimethylstibine oxide ((CH 3 ) 3 SbO) and a range of cyclic and linear oligomers have been detected using positive ion electrospray and atmospheric pressure chemical ionization techniques and the mass spectroscopic (MS) features are discussed. Dimethyl antimony ((CH 3 ) 2 Sb) species were not detected under the conditions used. The results from both MS techniques were similar. Copyright © 2001 John Wiley & Sons, Ltd.
