Abstract

The strengths of 619 experimentally recorded spectral lines (Jmax = 24) of the ν4 and ν2 bands of 28SiD4 were determined from the fit of their line shapes with a Hartmann–Tran line profile and were used then in the weighted fit for determination of the effective dipole moment parameters of these bands. The obtained set of four parameters reproduce the initial experimental line intensities with the drms=5.61%. A list of transitions with their line intensities is generated up to the value of quantum number J=37. The half–widths analysis was made on the basis of the multi–spectrum fit with the Hartmann-Tran line profile, and self–pressure broadening coefficients were estimated for 60 lines of the dyad.
