In this paper we report on a study by FTIR spectroscopy of the gas phase thermal decomposition of [Y(TMHD)3], [Cu(TMHD)2] and [Ba(TDFND)2,tetraglyme] under a total pressure of 10 Torr, for a temperature range 200 - 650°C, and in the absence and presence of oxygen. The variation of the decomposition characteristics for each of the complexes as a function of temperature, and as shown by changes in the absorption coefficients, are related to the molecular structures.
