WebIR spectroscopy of diphenyl acetylene shows no peaks (not even peaks corresponding to triple bond). This is because of the fact that IR spectroscopy relies on bond vibrations that change the dipole moment of those bonds. Bonds whose dipole moments do not change during vibration (nonpolar bonds) will not show a peak in the IR spectrum. popular european clothing storesWebExperiment 10 – Two-Step Synthesis of Diphenylacetylene from trans-Stilbene pg. 3 Figure 6.
