IR spectroscopy notation?

  1. Nov 11, 2012 #1
    Hi there. First time PF poster. I have a question about interpreting IR spectro graphs. I get the general idea of interpreting the sharpness and strength of the line but when I need to ID the pulse down I have to choose between [itex]\delta[/itex] and [itex]\upsilon[/itex] (or mabe its just v) version of the functional groups. I tried to correlate the usage b/w the fingerprint (400-1500 cm-1) and the functional (1500-4000 cm-1) regions and haven't seen the light yet. Thanks

    I don't understand what you mean by delta or nu versions of the functional group. The fingerprint region is pretty useless in finding out what functional groups are present btw. Could you state your question more precisely?

    I think I found out it represents a stretch or a bend. Thanks for the reply
