Hi Mike, sorry I haven't had time to search my "archives" for an IR of this compound - you may have to go to the original journal literature, such as Inorganic Chemistry from around the 1960's or earlier, via a Chem Abstracts search, to find a published spectrum. I guess your Jolly text does not have a literature citation.
Yes, perchlorates can keep you on your toes! I've seen a perchlorate explosion or two myself; resulting from simply scraping compound from the flask - dangerous stuff. Did your text say why the perchlorate salt was preferred over, say, nitrate?
I'll do some looking, although if I turn anything up it will probably be too late to do you any good for your report. It would have been appropriate to have at least mentioned the IR features in Jolly, to aid in characterization. Perhaps the visible spectrum was of greater interest, given the vivid color of the compound.
