THE INFRARED SPECTRUM OF HYDROGEN FLUORIDE: LINE POSITIONS AND LINE SHAPES

Abstract

The true shape of the rotational absorption lines of the hydrogen fluoride fundamental band was investigated. The line shapes were to be measured at pressures where pressure broadening made the only significant contribution to the true line shape. The experimental aspects of this investigation are discussed. All data were taken with the vacuum-grating spectrograph recently completed at the University of Tennessee. The results of the line center and line shape measurements are presented. Twentyone fundamental and seventeen first overtone line centers were measured at low pressure with an estimated accuracy of ! 1/0.02 cm. The fundamental and first overtone band centers were calculated to be 1/3961.43 cm and 1/7750.83 cm, respectively. The results of this investigation and suggestions for future experiments in this field are presented.
