Guess I should go ahead and ask the naive question, since I was
totally unaware of the RO function on Bruker spectrometers: what
is the utility of having variable spin rate? I thought it might
be to "blur" spinning sidebands when looking at very low intensity peaks
close to a solvent peak, for example; but not only could the spin rate
be changed to get around this (I think a better solution), but on our
AC's the variable rate change is so slow as to still give clean
sidebands during a nominal AQ.
Is there some application that I am not seeing where this function
becomes valuable?
