Title: $U(\Delta J - +4)$ TRANSITIONS AND OVERLAP PARAMETERS FOR $H_{2}-Ar$ MIXTURES*
Creators: Hsieh, C. T. W.; Reddy, S. Paddi

Abstract: Collison-induce enhancement absorption spectra of the fundamental band of-absorption-spectra of the fundamental band of $H_{2}$ in $H_{2}$ - Ar mixtures were recorded with a 2 m absorption cell for total gas densities up to 500 amagat at room temperature and up to 160 amagat at 201 and 273 K. In the spectra obtained at room temperature, the hexadecapole-induced transition U1(1) corresponding to the rotational selection rule $\Delta J = +4$ has been observed. From the analysis1 of the observed experimental profiles using appropriate line shapes functions and numerical values of the matrix elements of the quadrupole moment of $H_{2}$, characteristic half-width parameters $\delta_{d}$ and $\delta_{c}$ of the short-range overlap-induced transitions and $\delta_{q^{2}}$ and $\delta_{q^{4}}$ of the quadrupole-induced transitions have been determined. The overlap parameters of the induced dipole moment of $H_{2}$ - Ar pairs have also been determined. The absorption coefficient of the $U_{1}(1)$ transition is also estimated.
