Individual strengths of 358 (Jmax=28) ro-vibrational lines of the ν3 band of 28SiD4 were obtained from an experimental Fourier transform spectrum by the fit of their shapes with the Hartmann–Tran line profile. They were used in the weighted fit for determination of the effective dipole moment parameters of the ν3 band. Three effective dipole moment parameters were obtained which reproduce the experimental line strengths with the drms=4.0%. A list of 8125 transitions of the ν3 band with their line strengths was calculated up to J=43. The half-widths analysis was made on the basis of the multi-spectrum fit with the Hartmann–Tran line profile. Self line broadening coefficients were estimated for 72 isolated lines of the ν3 band.
