Abstract
The absolute infrared absorption intensities of the fundamental vibrations of HCN and DCN have been measured, using the pressure broadening technique. These measurements yield the bond moments μC–H=±1.13d, μC≡N=±1.80d and show that if C is positive in the C≡N dipole, H is positive in the C–H dipole. The change in moment with internuclear distance is found to be ∂μ/∂rC–H=±1.05d/A, ∂μ/∂rC≡N=∓0.66d/A. Two of the three anomalous peaks in the band ν1 of HCN are shown to arise from the dimer of HCN.
