Abstract
The infrared spectra of three bending fundamentals (ν5, ν6, and ν7) of gaseous cyanoacetylene and cyanoacetylene-d have been measured and their integrated absorption coefficients A(νi) have been determined. The spectral pattern of ν5 fundamental region in HCCCN has been interpreted by assuming the Fermi resonance between v5=1 and v7=3 states. On the basis of the experimental intensity data and the normal coordinate treatment, the dipole-moment derivatives with respect to the internal bending coordinates have been calculated.Keywords
