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 8020 mixture of N2O2. Both natural water and a special sample of deuterium depleted water one-fiftieth the normal concentration were used.
