Line Intensity Measurements of theν7+ν8Band of Ethylene (12C2H4)

[摘要] From the four high-resolution FTIR absorbance spectra recorded at a spectral resolution of 0.0063 cm−1, 123 line intensities belonging to theν7+ν8band of12C2H4were measured and fit. The upperv7+v8=1state rovibrational constants up to sextic terms determined using a Watson'sA-reduced Hamiltonian model inIrrepresentation were used to calculate the line intensities of the band.Results of the experimental fit of the line intensities agree well with those obtained by calculations.
