AN EXAMINATION OF THE FAR INFRARED SPECTRUM OF HYDROGEN FLUORIDE.
Abstract
The purpose of the investigation was to determine the frequencies, the ground state rotational constants, the intensities, and the half widths of as many of the pure rotational absorption lines of hydrogen fluoride as could be measured. The problem, in part, required the development of a far infrared spectrometer. This was accomplished by the redesign and reconstruction of a PerkinElmer Model 12B prism instrument. The general techniques of far infrared instrumentation are discussed in detail and their application to this particular instrument explained. The vacuum wave numbers of the line centers of the first seventeen lines of the pure rotational spectrum of hydrogen fluoride were measured. These lines map the region between 41.08 cm(-1) and 658.54 cm(-1). The equivalent widths for fifteen lines were measured at several different pressures and found to be directly proportional to the pressure over the range of measurement. (Author)
