Abstract

I. The infra-red and Raman spectra of Mn(CO)₅Br as both solid and CH₂Cl₂ solution from 50 to 2150 cm^-1 are presented for the normal isotopic compound, and the ¹³CO and C¹⁸O substituted molecules. The observed bands are assigned, and the force constants and compliance constants of a general quadratic potential field are calculated using the FG method of Wilson, Decius, and Cross.

II. The infra-red and Raman spectra of both Mn₂(¹²CO)₁₀ and Mn₂(¹³CO)₁₀ as solids and in CH₂Cl₂ solutions from 50 to 2150 cm^-1 are presented and are assigned. Potential constants are calculated using values transferred from the Mn(CO)₅Br calculations. Special attention is paid to splitting interactions across the Mn--Mn bond and to the Mn--Mn stretching potential constants.

III. Raman intensities and the electronic absorption spectrum of M(CO)₅X^n- compounds are presented and discussed.
