Water Vapor Continuum Absorption in the 3.5 Micrometers to 4.0 Micrometers Region.

Abstract

Measurements of water vapor continuum absorption in the 3.5 micron to 4.0 micron region are presented. The measurements were made with both long-path absorption cell and spectrophone systems. A deuterium fluoride grating tunable laser was the infrared source. Measurements were made at 23 C and 65 C with 14.3 torr and 65 torr of water vapor, respectively, buffered to 760 torr total pressure by an 80/20 mixture of N2/O2. Both natural water and a special sample of deuterium depleted water (one-fiftieth the normal concentration) were used.
