A line tunable deuterium fluoride laser was used to measure the pressure dependence of the water vapor continuum absorption at 25 degrees C in the 3.5-4.0-microm spectral region. From measurements of the absorption of 14.3 Torr of deuterium depleted water vapor buffered by several air-broadening pressures, an unexpectedly small foreign-to-self-broadening coefficient of 0.011 with a factor of 2 uncertainty as well as an unusually strong self-contribution for the water vapor continuum absorption were observed. These measurements can be used to infer contributions to the water vapor continuum in the 3-5-microm window from both far wing and aggregate-water-molecule type absorptions.
使用一台线可调氟化氘激光器测量了25摄氏度下3.5 - 4.0微米光谱区域内水蒸气连续吸收的压力依赖性。通过测量在几种空气增宽压力缓冲下14.3托贫氘水蒸气的吸收，观察到意外小的0.011的外来与自增宽系数，其不确定性为2倍，并且水蒸气连续吸收存在异常强的自贡献。这些测量可用于推断3 - 5微米窗口内水蒸气连续吸收中来自远翼和聚集水分子类型吸收的贡献。
