New Methods for Acquiring IR Spectral Data in Organometallic Chemistry and Catalysis

Abstract

The advent of new infrared sampling accessories has allowed in situ study of organometallic systems under conditions that were previously not readily accessible. The techniques of Cylindrical Internal Reflectance (CIR) and Diffuse Reflectance spectroscopies are described herein. The CIR phenomenon was employed in three different apparatus. Two different high pressure CIR cells were used to study reactions homogeneously catalyzed by [μ-HW_2(CO)_(10)]^-. Low temperature reactions of Mo and W complexes were studied using an ambient pressure CIR cell. The diffuse reflectance technique was employed to study powdered samples of Ru carbonyl complexes supported on Al_2O_3
