Hello everyone!
I want to know the structure of chromite clusters in aqueous solutions. Is there any spectroscopic technique to determine their structures? Recently, I measured mass spectroscopy of chromite solutions. However, the sample for mass spectroscopy should be extremely sparse, i.e. very low concentration, which may form different structures rather than the oligomers in dense solutions. Can you tell me some solution based spectroscopy method to determine the cluster structure of solutions? In fact, I mixed CrCl3, Fe(NO3)3 and Dy(NO3)3 solutions together, and added some KOH into the mixed solution, which is a key process for the synthesis complex structure oxides and hydroxides. Thank you for any concerns and possible suggestions.
