Vibrational assignments for Hg(C2H5)X (X Cl, Br or I) and HgBr(C2D5) are proposed, on the basis of solution studies as far as possible. For the bromides, 21 force constants are refined in the presence of 12 constrained values from C2H5Cl and 12 of these are used as additional constraints in refining 9 force constants for the chloride and iodide. The nature of the normal modes of Hg(C2H5)C1 is discussed. The Hg-C stretching force constants of the ethyl compounds is marginally higher than in corresponding methyl derivatives.
