    IR Spectra: Why is CO2 a doublet at 2350cm-1?

    CO2 is supposed to create a "doublet" peak at 2350 cm-1 according to my IR correlation chart. Why is this doublet created? As DrDu explained in my previous post, two peaks are seen for the N-O bond because it has IR-active symmetric and asymmetric stretches. But CO2 is a linear molecule, and...

    IR Spectra: N-O Nitro group: Why two peaks?

    That makes sense, thank you! In the same vein, I notice that my correlation chart also has the carbon dioxide stretch listed as a "doublet" appearing around 2350 cm-1. Is that for a similar reason as N-O/CH3? In my mind it shouldn't be, because CO2 is not bent and does not have resonance, so the...

    IR Spectra: N-O Nitro group: Why two peaks?

    My IR spectra correlation chart for organic chemistry says that the stretch for a nitro N-O bond occurs at "1550 and 1400cm-1" and that it will look like "teeth". Why does N-O have two peaks? The rest of the functional groups on my chart list a range in which a single peak should appear, but why...
