Measurements of anomalous atmospheric absorption in the wavenumber range 4 cm-1.
Abstract
Field measurements have been made of atmospheric absorption in the wavenumber range (4-15)/cm, using a 200-m horizontal transmission path at a resolution of 0.2/cm. The results are compared with theoretical spectra based on water-vapor monomer absorption, and anomalous absorption spectra are presented. There is support from some preliminary laboratory work. A binding energy of between 0.4 and 0.8 electron volts per molecule is derived for the water-vapor complex responsible for the absorption.
