    Any hints for the copper level question? I'm only a GCSE student

    thanks
    I believe something you may cover at GCSE physics will give you a clue as to what the lines might represent. However, you'll need A2 physics or good googling skills for what 8->4 represents.

    haha well that leaves it either being a decimal or an incredibly cruel large number!

    Gold is frustrating my life. If anyone can PM me the answer, I would be very grateful.

    Arrrgh can someone hint me the last question please? Sooo confused

    (Original post by david2457)
    I am loosing ideas for the last question. May not even be NMR. If someone has a breakthrough or knows it, message me, thanks

    Not a clue! I was thinking NMR peaks, but the more I try to do it the less I think that it is NMR.

    Has anyone actually done Rg?!

    I am just going to go back to my GCSE Biology revision. Rg is just too hard!
    Ok, to everyone stuck on Rg. You're going to need A2 Chemistry (or at least, that's where I covered it), or be able to learn quickly from the very poor internet sources that exist.

    GreenLantern is on the right track with C13 NMR

    Yes you can manage it with good googling skills don't worry
    I found the answer on wikipedia.
    I started with something I had a clue about:

    That being said, I think a page in my exam notes may help, if people wish to try learn. Page 16 of attached notes:

    Think about the Carbon Environments in each molecule for Rg. I needed help myself, only being 15 and doing my GCSEs

    I'm completely stuck, I've used a bit of software called ChemDraw to find the number of peaks in 13C NMR and when you multiply them together, it doesn't work. It works for the top line, 1 for C60, 2 for Adamantane and 4 for HNC, but it doesn't work for Nano chef x Mescaline x Rhodamine 123 (There's a clue for people who haven't even got that far yet) so I don't know what to do, and I can't see the relevance of the exponential sound decay is though? anyone got any ideas on how to go about it (and don't ask me for the 13C NMR, I'm sure you can all work it out! I've done it both ways and they both give the same answers.)

    I am 15 doing my GCSEs as well and I have worked out about the NMR peaks and had some help with C13. But I can't clue together the carbon environments for each molecule!!!!
