USE OF LASER RADIATION TO DETERMINE SCANNING FUNCTIONS; AND LINE WIDTHS AND INTENSITIES OF NU 2 WATER VAPOR LINES.
Abstract
Measurement of the correlation function at a slit in the case of an Hg source by the method of Beran and Parrent gives results which are in agreement with Hopkins' concept of an 'effective source.' Results using a laser-integrating sphere source indicate that it may be used interchangeably with an ordinary 'incoherent' source for scanning function calibration. Absorption spectra of pure water vapor and mixtures of water vapor with air were measured, in wings of the nu-2 band at 400K and 540K. Vibration rotation interaction in this band was measured by relative intensities of rotational lines. Line widths of the rotational transitions for self broadening were found to decrease with a temperature rise: for broad and strong lines approximately inversely proportional to absolute temperature.
