Continuous, emission, and absorption spectra The water vapor continuum absorption spectrum is retrieved using the known absorption in the 2500 cm−1 region as a reference point. It is shown that the continuum absorptions in four windows differ Water vapor continuum absorption in the 3.5-4.0-,um region Kenneth 0. White, Wendell R. Watkins, Charles W. Bruce, Robert E. Meredith, and Frederick G. Smith Measurements of water vapor continuum absorption in the 3.5-4.0-gm region are presented. From observation, the in-band continuum absorption is aligned with the location of the water vapour monomer bands; therefore, any interaction between the absorbing water vapour molecule and another molecule (water vapour or ‘foreign’) that is responsible for this additional absorption must be sufficiently weak so as to permit access to the same rotovibrational modes of monomer transitions and sufficiently brief to cause these transitions to be greatly broadened. The water vapor continuum absorption spectrum is retrieved using the known absorption in the 2500 cm−1 region as a reference point. It is shown that the continuum absorptions in four windows differ Abstract Collision-induced absorption coefficients for the 1.27 υm band of O 2 have been measured at a resolution of 0.5 cm-1 and an optical pathlength of L = 84 m using a Fourier-transform spectrometer and 2 m long White-type multipass absorption cell. The accurate modeling of continuum absorption is crucial for the so-called window regions of the spectrum, the relatively transparent regions between lines.

The length-stabilized ring-down cavity rests inside a 110 cm long, 10 cm diameter temperature-controlled cell with a gas volume of 6 l. - "Infrared water vapor continuum absorption at atmospheric temperatures." We can examine them to determine many properties, among them the radial velocity of the galaxy, the star-formation rate, and the average age and metallicity of the stellar populations, and the kinematics (mass) of the galaxy. A spectrum has three components: the continuum, absorption lines, and emission lines. Thus, absorption by the water vapor continuum represents some, but not all, of the absorption by water vapor.

The THz pulses propagate though a 137 m long humidity-controlled chamber and are measured by THz time-domain spectroscopy (THz-TDS). The average relative humidity along the entire THz path is precisely obtained by measuring the difference between transit times of the sample and reference THz pulses to an The continuum As is well known, the spectral line profiles in a wing absorption dominates in atmospheric transparency differ for different absorption bands [4–7]; therefore, windows. the continuum (used in MT CKD model) obtained The comparative smoothness of the continuum on the basis of the unified line profile model, and absorption curve turned out to be a cause of the experimental data in The MT_CKD continuum model includes continuum absorption due to water vapor, nitrogen, oxygen, carbon dioxide, and ozone. With respect to water vapor, the contributions of the foreign and self continuum are considered separately.
