Ir spectra of diphenylacetylene
WebCompound 2 has been characterized using IR, 1H and 13C NMR spectroscopy; the tetrahedrane-type cluster framework has been ascertained using a single-crystal X-ray diffraction study performed at 100 K. 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.
