WebJan 30, 2024 · It is easier to bend a molecule than stretch it, hence stretching vibrations have higher frequencies and require higher energies than bending modes. The finger print region is a region from 1400-650 cm-1. Each molecule has it's own characteristic print and is often cumbersome to attach any values to this region. Figure 6 IR Spectrum of … WebAs for H 2 O, there are 3 vibrations: 2 stretches and 1 bend. Although each C=O bond in CO 2 is polar, its linear shape means that the molecule as a whole does not possess a dipole moment. During the asymmetric stretch and bend, the symmetry is lost and a dipole is momentarily created. It is possible to excite these 2 vibrations with IR radiation. diesel shirt gr m t-shirts
