Individual contributions of the far-wing (beyond 25 cm-1), near-wing (within 25 cm-1), and basement components to the total continuum absorption based on the use of CKDv0 (see Section 3 and Subsection 4.A).
We present an experimental study of the self- and N2-broadened H2O continuum in microwindows within the ν2 fundamental centered at ~1600 cm-1. The continuum is derived from transmission spectra recorded at room temperature with a BOMEM Fourier transform spectrometer at a resolution of ~0.040 cm-1. Although we find general agreement with previous studies, our results suggest that there is significant near-wing super-Lorentzian behavior that produces a highly wave-number-dependent structure in the continuum as it is currently defined.
Founded in 1916, the Optical Society of America (OSA) was organized to increase and diffuse the knowledge of optics, pure and applied; to promote the common interests of investigators of optical problems, of designers and of users of optical apparatus of all kinds; and to encourage cooperation among them. The purposes of the Society are scientific, technical and educational.
The Optical Society of America brings together optics and photonics scientists, engineers, educators, and business leaders. OSA's membership totals 15,500 individuals from over 95 countries. Approximately 47% of the Society's members reside outside the United States.
