×öÒ»ÏÂÎij¹«£º C¨CH stretching bands from aliphatic compounds occur in the range 3000¨C2850 cm-1. If the C¨CH bond is adjacent to a double bond or aromatic ring, the C¨CH stretching wavenumber increases and absorbs between 3100 and 3000 cm-1. The only one of these single bonds of any value is C¨CO which is polar enough and different enough (Table 3.7) to show up as a strong absorption at about 1100 cm¨C1. The region below 1500 cm¨C1 is where the single bond vibrations occur. |
