INFRARED STUDY OF THE HYDROGEN-BOUNDED, HIGH-BOILING ORGANIC COMPOUNDS ISOLATED IN THE LOW TEMPERATURE INERT GAS MATRIX.

Author Institution: Chemical Physics Research Laboratory, The Dow Chemical CompanyThe low temperature matrix isolation technique has been used by infrared spectroscopists for more than ten years in the study of low-boiling compounds, unstable molecular species and very high-boiling inorganic compounds. However, little information can be found in the literature about the matrix isolation of the strongly hydrogen-bonded solid organic compounds for analytical studies. This paper reports a matrix isolation device which can be used to isolate the monomer of the hydrogen-bonded organic compounds, liquids or solids at room temperature, in a low temperature inert gas matrix. The isolation can be achieved in a reasonably short time and this device can be used repeatedly for different samples in routine analysis. Infrared spectra of the matrix isolated pyrazole, imidazole, pyridinols and some other hydrogen-bonded compounds will be discussed
