Line intensities of H2CO are analyzed between 1148.4 and 1192.8 cm-1 by taking into account the Coriolis interaction involving the ν4 and ν6 fundamentals. Finally two intensity parameters can be significantly determined: ∂μy/∂q4=0.0592±0.0018 D and ∂μx/∂q6=0.0772±0.0019 D. From these results, the ‘‘deperturbed’’ band strenghts can be calculated: S04=20.9±1.3 cm‘u-2 atm-1 and S06=38.0±1.9 cm-2 atm-1 at T=297 K. [ABSTRACT FROM AUTHOR]
