Star-formation in the central kpc of the starburst/LINER galaxy
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 window regions in the microwave are of critical importance for Earth remote sensing and data assimilation. 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.
But it is hard to believe that far wings of water dimer bands, presumably detected in recent works by Paynter et al. and Ptashnik et al. , may be predominant in comparison with far wings of water vapour CIA bands.

The continuum radiation absorption cross sections of a C - H - O - N ablation system were examined in detail. The present computer code was evaluated and updated by being compared with available exact and approximate calculations and correlations of experimental data. absorptionline spectra. We can think of stars as a hot continuum source with a "cool" atmosphere of absorbing gas. The wavelengths that get absorbed depend on the chemical make up of the gas in the stellar atmosphere. In the 1800's the light from the Sun was dispersed and it looked The continuum absorption by H 2 O has several characteristics that are common throughout the windows in the infrared and millimeter-wave regions. Values of the continuum absorption coefficient calculated on the basis of simple, widely used line shapes may differ greatly from observed values in the windows between strong absorption lines.

The continuum is a convex hull fitted over the top of a spectrum to connect local spectrum maxima. The continuum absorption can be unambiguously determined from measurements in the band wings if one assumes that it is purely continual there. Within bands, the continuum absorption cannot be determined unambiguously and depends on the local line contribution boundary chosen.
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 first two corrections involve an improved fit to the pure water vapor continuum absorption together with the elimination of the atmospheric broadened continuum term. Finally, and most critically, a strong measured temperature dependence must be included in the water vapor continuum absorption … the physical origin of the water vapour absorption continuum are a long-standing issue in molecular spectroscopy with di-rect impact in atmospheric and planetary sciences. In re-cent years, we have determined the self-continuum absorp-tion of water vapour at different spectral points of the atmo- Absorption is the process by which a photon is absorbed by the atom, causing an electron to jump from a lower energy level to a higher one. The process is described by the Einstein coefficient (m 3 J −1 s −2), which gives the probability per unit time per unit spectral radiance of the radiation field that an electron in state 1 with energy will absorb a photon with an energy E 2 − E 1 Determination of the water vapor continuum absorption from 0.35 to 1 THz is reported.
