### Abstract

The vibrational spectra data, the assignments, and the results of normal coordinate calculations for CH_{4 - n}(HgCH_{3})_{n} molecules (2 ≤ n ≤ 4) are reported. The central CHg valence force constants are 1.870, 1.653, and 1.582 N cm^{-1} while the terminal ones are 2.121, 2,101, and 2.160 N cm^{-1} for n = 2, 3 and 4, respectively. The latter values are 12, 21, and 27% higher than the central CHg force constants, but all of them are substantially lower than those in dimethylmercury (2.379 N cm^{-1}). These findings can be accounted for in terms of increasing shift of electron density towards the periphery of these molecules and increasing non-bonded metal-metal interaction. The nature of the normal modes is discussed.
