Water Vapor Measurements between 590 and 2582 cm-1: Line Positions and Strengths.

This study involves measurements of H216O, H217O, and H218O vapor spectra for the region between 590 and 2582 cm-1. The parameters derived from the data include line positions, energy levels, and linestrengths. The study involves high-resolution line-position measurements with samples at room temperature in the (000)-(000), (010)-(010), and (010)-(000) bands. The experimental frequencies were used along with microwave, far-infrared, and hot water emission measurements in an analysis to obtain high-accuracy rotational energy level values in the (000), and (010) vibrational states of H216O for J </= 20. The experimental linestrengths were fitted by least squares to a model in which the dipole moment was represented as a series expansion containing up to 19 dipole moment matrix elements. The measurements in this work were more extensive than reported in prior studies by this author for the (010)-(000) band. Copyright 1998 Academic Press.
