Abstract

The pressure-narrowing theory of Galatry is applied to the calculations of equivalent widths of lines in the quadrupole rotation-vibration spectrum of molecular hydrogen. The theory leads to agreement with the measurements of Rank and associates. A value for the pressure-broadening coefficient of 0.0015 cm<sup>-1</sup>/atm at 300 K is obtained for the 1-0 <i>S</i>(1) line. The application of the results to the hydrogen abundance on Jupiter is briefly considered.
