Sulfur-containing compounds ambiguities

It is to be recalled that not only is there ambiguity as to the products of combustion of any antimony-containing species (cf. Reference 28), thermochemical studies of sulfur compounds show related complications. (See for example, the discussion in W. N. Hubbard, D. W. Scott and G. Waddington, in Experimental Thermochemistry Measurements of Heats of Reaction (Ed. F. D. Rossini), Interscience, New York, 1956.)... 

The method has its limitations—many of them due to the limitations of the AMI procedure itself, which, for example, was not parametrized for compounds containing hypervalent sulfur and phosphorus [34] at the time of development. Nevertheless, with this method, there is never any ambiguity as to how to divide the whole compound into different fragments or functional groups and since the concept and idea are very straightforward, there is no need (or possibility) to introduce correction factors. As an additional advantage, for compounds that can have stable isomers, this method may be able to differentiate among them, even if differences may sometimes be small [35].
