We performed IR Spectra on some unknowns and we must determine
the unknown based on the spectra. I understand that I need to
identify the wavelengths of the peaks in order to determine the
bonds and groups present, but I don't understand how to take that
knowledge and figure out which molecule is my unknown. The
molecules pictured at the top of the page the the ones that could
potentially be my unknown.
