INFRARED SPECTRUM OF HYDROGEN FLUORIDE: SHAPES, POSITIONS AND INTENSITIES OF HIGH J LINES IN THE FUNDAMENTAL BAND
Abstract
The aim of this investigation was to determine experimentally the true line shape and line position for as many as possible of the high J rotational absorption lines in the hydrogen fluoride fundamental band. The line shapes were to be determined at identical temperatures and at pressures where pressure broadening made the only significant contribution to the line shape. All data were taken on the high resolution vacuum-grating spectrometer. The HF lines were used as internal standards for calibrating purposes. The R(5) line of the first overtone of CO was used to determine the slit function to correct measured line shapes for distortions caused by instrumental broadening. The line position of R(11) was measured to be 4320.97 waves per cm. The line shapes of R(9), R(10), and R(11) were determined and found to be truly Lorentzian.
