Abstract
From the pure rotational spectra of several different isotopic species of CH3HgCl it is shown that dCHg=2.061±0.02A, dHgCl=2.282±0.005A, and ∠CHgCl=180°. Similarly, for CH3HgBr it is shown that dCHg=2.074±0.015A, dHgBr=2.406±0.005A, and ∠CHgBr=180°. Nuclear quadrupole couplings evaluated are Cl35=—42 Mc, Cl37=—33 Mc in CH3HgCl, and Br79=350 Mc, Br81=290 Mc in CH3HgBr. These indicate ionic character of 62 percent for the HgCl and 55 percent for the HgBr bond in these molecules, and lead to a value of 1.7 to 1.8 for the electronegativity of divalent mercury.This publication has 9 references indexed in Scilit:
