im interested in finding out the molecular size of "acid blue 113" dye molecule. is zetasizer a perfect instrument to do that? im just wondering if the molecular size is already available in online sources like "PubChem"? If so please share the link or concerned literature. Thanks

The molecular weight of the dye is only 681, so if it is completely dispersed instead of aggregated, it is probably too small to measured by light scattering. It should be possible to calculate the size based on the chemical structure.

Dear Adam Shapiro,
Did you mean : "measuring the molecular size by summing up the various bond lengths from the molecular structure?"
Regards,
Gopi

Summing up the bond lengths is not a good way because it does not take into account the bond angles. There are various ways to describe the size of a molecule, such as the longest distance across the molecule, or the total volume. Talk to a nearby computational chemist to get some advice on how to calculate the dimension of interest to you.
