    I'm really stuck on gold! I know it's the nanokid and something to do with the IR spectrum, but I don't know what to do now, please help!

    It's the nanoballet dancer. Look up degrees of vibrational freedom.

    I know exactly what I'm looking for with Gold (I know what the molecule is and what the numbers mean) but I don't know how to find the answer. Can anyone help me out? It's really annoying me
    There's a formula to calculate it. It's on the wikipedia page.

    If you still require additional help:
    For a general (non-linear) molecule with N > 2 atoms an N-atom molecule has 3N - 6 vibrational degrees of freedom

    Taken from: http://en.wikipedia.org/wiki/Degrees...and_chemistry) if you wish to read a bit more about it

    Really stuck on Copper... Just can't work out what to do.

    Any help?
    Another hint to find the compound displayed, is the object it is made of.

    the volume of the arena is: [50*(365/2)*(365/2)*4pi/3]/2 .... then get it to liters cause it is in cubic meters...for total moles divide by 0.082*273 ... for oxygen moles: multiply by 21% and then by the abundance of each isotope....for the answer multiply by the molecular weight (35.. or 34 it really doesn't matter) and that should be it....
    I did exactly this but it does't seem to work out...

    First look at what the molecule is made of, that should give you a hint as to what it is.
    Also, what really helped me was knowing what the symbol was (before max), think about greek letters.
    Maximum wavelength, but I'm drawing a blank and can't figure out what the pink stuff is. Clay? Gum?

    You beat me, I didn't manage to finish RG until after sixth form.:ashamed2:. I came 141st (Alexander H.) :cry:. The first one took me such a long time to do though.
