Hi,

Has anyone found any good sources of notes for these two units online?

Thanks.

I'm feeling quite confident about 331, just the bond angles I need to get sorted!

you?
Does anyone have a set answer for Q's that ask to describe the emission/absorbtion spectra ?

You'll probably need to ask your teacher as they are in a password protected section of the OCR website.

Unless someone on here has a password!

An emission spectra has coloured lines on a dark background, at specific frequencies. The frequency of the line is determined by the difference in energy between two energy levels (as E=hf). As the energy levels are unique to an element, the frequencies emitted are unique to the element, and as the energy levels are discrete, the same frequencies will be emitted. This means the emission spectra is unique to the element.

You probably don't need to say all of it, but I included everything in case there's a three mark question it or something.
