A Multisurface Matrix-Isolation Apparatus

Abstract

A multisurface matrix-isolation apparatus has been designed and interfaced to an FT-IR vacuum spectrometer. The design permits independent matrix-isolation studies with sixty different surfaces. It also allows direct measurement of matrix gas to guest ratios with an integral cooled quartz crystal microbalance. Problems associated with moving the matrix block while maintaining good thermal contact are discussed. Finally, some applications to studies of coal pyrolysis, metal atom chemistry, and quantitative analysis are presented.
