Inorganic germanium(I1) in micromolar concentrations was reacted with methyl iodide (CH3J) and methylcobalamin (CHJ-CoB,,) at various pH values and with different salt matrices. In all experiments monomethylgermanium was the only product. The reaction with CH,-CoB,, at pH1 yielded approximately 1.3%
Raman spectroscopic measurements were performed on solutions (0.02 O [ As ] O 5.2 mol kg-1) at As 2 O 3 -H 2 O temperatures from 20 to 275 ΓC. At 20 ΓC the spectrum of arsenic solutions of low concentration (0.02-0.5 mol kg-1) is the same over a wide range of pH (0-8). It only exhibits a polarized b
